Generation of different length PN sequences including the maximally long LSFR could be demonstrated and compared with calculated results. This permitted acquiring and analyzing the output stream using a simple dumb terminal.Ī 8-bit DIP switch permits setting up of desired feedback combinations from the eight shift register outputs. Additional circuitry was added to convert and send the 1's and 0's output of the LFSR as ASCII serial data '30','31' Hex. This project implements a pseudo-random (PN) sequence generator based on a 8-bit linear-feedback shift register (LFSR). Surprisingly the breadboard hardware which was recently returned to me and had not been powered for 30 odd years worked perfectly when powered ON. This is revisit of a student project I mentored back in 1990-91.
