Abstract
A delta-sigma converter and corresponding decoder employing predetermined characteristics of readily available logic elements. The converter is realized through the use of an integrator responding to an analog input signal and a dual D flip-flop package having a high impedance, comparator functioning input and low impedance output to act as a switch to control the integrator. Switching of the flip-flop acts to provide pulses at a rate corresponding to the analog input signal level.
