Linear-Segment Function Generator

A single-variable function generator, based on a pulse averaging method,1 accepts a width-modulated pulse input. The clock generator accuracy determines the precision with which this device can produce a linear-segment curve. With 300-kc flip-flops in the clock, a static repeatability of ±0.02 per cent has been obtained with a carrier frequency of 100 cps, and ±1 per cent with a 10-kc carrier frequency. This device can multiply the single-variable function by a second input variable at no loss of accuracy and with no additional circuitry.
