The PEAR program has used three generations of random event generators, with different primary sources of white noise, but important common features of design. The original "benchmark" experiment used a commercial random source developed by Elgenco, Inc., the core of which is proprietary. Elgenco's engineering staff describe the proprietary module as "solid state junctions with precision pre-amplifiers," implying processes that rely on quantum tunneling to produce an unpredictable, broad-spectrum white noise in the form of low-amplitude voltage fluctuations. The PEAR Portable REG uses Johnson noise in resistors, which is so-called "thermal noise" and is also a quantum level phenomenon that produces a well-behaved broad-spectrum fluctuation. The PEAR Micro-REG uses a field effect transistor (FET) for the primary noise source, again relying on quantum tunneling, and providing completely uncorrelated fundamental events that compound to an unpredictable voltage fluctuation.
In all cases, the design begins with white noise, for example in the PEAR Portable REG, a flat spectrum +/- 1 db from 1100 Hz to 30 KHz. A low end cutoff at 1000 Hz eliminates frequencies at and below the data-sampling rate. This filtering, together with appropriate amplification and clipping, produces an approximate square wave with unpredictable temporal variation. Sampling at a constant 1 KHz rate is typical, although special sources have been constructed allowing higher rates (up to 2 MHz). Analog and digital processes are completely isolated by alternating these operations to exclude contamination of the analog noise train by digital pulses. To eliminate biases of the mean that might arise from such environmental stresses as temperature change or component aging, an exclusive or (XOR) mask is applied to the digital data stream. This is either an alternating 1/0 pattern or a more complex mask comprising an array of all bytes with equal occurrence of 1/0. Both exclude bias of the mean, in principle, and the latter also excludes all short-lag bit-to-bit and byte-to-byte autocorrelations. Finally, data for the PEAR experiments are recorded as "trials" that are the sum of N samples (e. g., 200 bits) from the primary sequence, thus further mitigating any residual short-lag autocorrelations. The result is a data sequence that conforms to the appropriate theoretical binomial distribution and to its normal approximation.
The final output of the PEAR devices is a sequence of bytes presented to the computer's serial port, which are then formed into a sequence of trials (typically sums of 200 bits), generated at 1 per second. Calibrations on all of the devices show behavior that closely models theoretical expectations for mean, variance, skew and kurtosis.
