Abstract :
A scheme for obtaining Nyquist information from a time domain, analog simulation is presented. The scheme is based upon a sampling technique which can be implemented by standard, analog computer circuitry plus some special purpose electronic circuits. Experimental results are given showing its application to linear feed-back control system simulations, including sampled-data systems.
