DIGITAL_FOURIER


Posted on Feb 4, 2014

Sine-wave generator produces Walsh-function approximation of sine function. Frequency of sine wave is set by square-wave input to pin 14 of 7493. Filter com ponents of opamp help smooth staircase wave form generated by summing Walsh-function components as weighted by resistors. Circuit is converter consisting of digital expander that expands input square wav..
