    In most places, you can call up and order what you want. They just bring in their own new wire. I have ordered services in some rentals I have been in with no problems. I now own, so it's not an issue. If your building owner forbids this, then it's a time to move. Lower property value due to lack of quality services may change the policy.

    I think by not implimenting it means the same thing as not having a Video Cypher II descrambler installed in your old C-Band receiver. It too was "optional". However without it and a paid subscription you could not get any "premium" content. Think if "optional" means "unable to", then think "the option is an added feature". It can receive the ball game, movie, PPV event... Devices not built with content protection will be unable to use protected content. Your unprotected TV on current cable without the cable company's decoder is a good example of this setup. I don't think a machine that descrambles scrambled content will be OK as defined by the DMCA.

    Take a working chip of anykind. Try something new like copper, silver, aluminum gold aloy, different transistor doping, interconnect size,. Get new equipment to process it. Discover copper, silver migrates into silicon and kills transistors. Try a few things to stop copper migration. Each experiment takes time and money to set up and the results are not known for a couple months because you have to make the IC to test it. When you are done 2 years later you have a 25% faster part. Now repeat with the next speed enhancement. It is not a conspiracy, it is the developement cycle. Rushing it means changing multiple things at the same time like changing lines, insutlaters, transistor size, doping, voltage, etc. all at once then not understanding why it doesn't work. Any single change usualy makes a device not work on the first try. The result needs examined and changes made to make it work right. Improvements are done from something working to somethnig unknown and making it work, then going on to the next change.

    There are transistors already out there that work near these frequencies. A quick search on google turned up this info on transistor technology.

    GALLIUM-ARSENIDE FET AMPLIFIERS have been developed which provide low-noise amplification up to about 30 dB in the 7- to 18-gigahertz range. The power output of many of these amplifiers is relatively low, approximately 20 to 200 milliwatts, but that is satisfactory for many microwave applications. Research has extended both the frequency range and the power output of gallium-arsenide FET amplifiers to frequencies as high as 26.5 gigahertz and power levels in excess of 1 watt in multistage amplifiers.

    The web page with this info is located at http://www.tpub.com/neets/book11/45o.htm. There is nothing preventing this being used for computing. Advances need to be made to provide syncronised clock signals to all the chip and the power consumption will need to be dealt with. These are analog devices at this time.

    . If what he is saying was true and there was 120 Ohms in series with the 8 Ohm speaker you wouldn't hear much through the speaker and the wire would probably get HOT! (Ohms law) He is basing his opinion on faulty logic. Electromagnetic waves don't behave the same at light frequencies as they do at radio frequencies and at audio frequencies ac behaves still differently.

    You missed the point. Take a length of 50 ohm RG-8 or RG-58 Coax of any length. Nowhere will you measure 50 ohms on it with an ohmmeter. It means 50 ohm cable with an 50 ohm load will not look inductive or capacitive to the source but purly resistive. With a load above the cable impedance the wire is capacitive, and at less than cable impedance load, the wire shows inductive reactance. A load at the wire impedance will show a pure resistave load at "all" frequencies including audio - RF. Can anybody say ruller flat response from DC-100MHZ? Last time I checked, inductance in a speaker line is bad for high frequencies. Impedance of a cable has nothing to do with series resistance. If that were true, you would want as close to zero ohm cable you could get for your network and radio antenna wires. Impedance is what resistance load the cable exhibits a balance between being capacitive or incuctive and transfers power most effeciently into the load. Impedance is fixed regardless of the cable length or frequency of operation. (unlike resistance) A longer cable has more capacitance, inductance and resistance, but the impedance stays the same. This is the load the capacitive reactance and inductive reactance balance and cancel each other out. The capacitance and inductance per foot is fixed. I hope this helps. By the way the resistive loss per foot is not the same for RG8 and RG58 even though they both have a 50 ohm impedance. I hope this helps. Impedance does not equal anything near DC resistance. Zero DC resistance in a wire including 50 ohm coaz and 120 ohm CAT 5 cable would be very nice. Zero resistance can not remove inductance or capacitiance from a conductor.

  7. Re:Separate amplifiers on What Audio System Powers Your Home Theater? · · Score: 2
    I agree, but the best advantage is the amps can be located at the speakers so the speaker wire does not reduce the damping ability of the amplifier.

    For anyone who does not what damping is, it is the ability of an amplifier to stop a moving speaker cone in it's tracks. A simple demonstration is take a speaker and disconnect it from a system and drum your fingers on the woofer. It will sound like a drum and the cone moves easily. Now put a short on the speaker terminals and drum again. The cone moves very little and the hollow drum sound is gone (in a good speaker) or reduced greatly. This is what damping is. It is the reason amplifiers have an output impedance of much less than one ohm. It's to keep the speaker from "ringing" after a transient event. That is damping. High resitance of long and or small gauge wire reduces the ability of a good amplifier to damp the speaker. The impedance marked on the back of the amp is the recomended impedance of the speaker load, not the output impedance of the amplifier. A speaker load impedance too low just draws too much current and overheats the amplifier. A good amplifier will have either the impedance marked in ohms or the damping factor which is the inverse of impedance. Hence an amp with damping of 60 has an impedance of 0.017 ohms. This is why long wires that are too small are detrimental to sound quality. (which is a good amp)

  9. Re:Warning: NOT under $1500 on What Audio System Powers Your Home Theater? · · Score: 1

    OOps on the wire. Speaker damping is the inverse of the impedance of the output of the receiver + the resistance of the wire. Only a fool uses 120 ohm impedance speaker wire in a high end system that is 22 or 24 AWG and expects the receiver to properly damp speakers with it's 0.02 ohm output impedance. The resistance of the wire reduces the damping ability of the speakers by more 10X if the wire has as little as 0.2 ohms or more. (resistance not impedance) Resistance affects the DC performance of a wire (damping & power handeling) & impedance affects the high frequency performance of the cable. Idealy, a cable should match to the speakers like a coax matches to an antenna. (remember RG58 network cable required 50 ohm terminations on each end?) Resistance should be very low to reduce loss and the wire impedance should match the load (speaker) impedance for flat frequency response. (no coloration) Most speaker cables have a higher impedance than the speakers. (20-120 ohm typical) Most manufactures do not advertise the impedance of speaker cable. Many people think high capacitive values kill highs in a speaker cable and avoid that wire, but it actualy counters the inductive impedance of the wire and is needed to lower the impedance of the cable to match the speaker impedance. Anybody who works a lot with RF knows this is a sound transmission line fact. Impedance mismatches screw up a system.

  10. Re:Yamaha! on What Audio System Powers Your Home Theater? · · Score: 1

    I like Yamaha, but my system doesn't meet the price requirement of only $1500. The speakers alone almost do, but not quite. Of all the components that change the sound with distortion and frequency range, the speakers make the most difference. Don't be cheap here. Get ones that sound like a cement block when you knock on them, not a hollow log or plastic bucket. They will be heavy and add the least coloration and distortion to the sound. Yamaha NS-1000's rock. There is a lot of discussion here on Bose. I have heard several Bose systems and I find due to the direct reflecting system, they do fill a room with sound, however the sound is heavely colored by the room accoustics which is ok for making a flat studio music recording sound alive, but I find movie stuff and live music altered by the Bose, so outdoor and other outside stuff still has a warm room sound. I went with the Yamaha Natural Sound system instead. If you are crampted for space, then the BOSE system is ok as your room has the acoustics of a small room or den anyway.
