Below some circuit typologies ranging from 3 up to 16 bits ( if you somebody wants I can explain how it works and provide the Verilog an C code ). I tested all the NLPRG sequences with a counter. Each path can have different amplitudes and delays. The LFSR is a pseudo-random generator circuit. For example, a 3-bit up-counter counts from 0 to 7 while the same order is reversed in the case of 3-bit down counter. On that dirk-gently-esque premise I’ve designed and built a 4-bit analog random number generator. In the present work, a set of M PRBS Correspondence to: D.
