Abstract
An apparatus for converting digital signals into analog pulse width modulated signals without a D/A Converter includes an up-down counter, programmed by the digital signal, which provides a signal to logic circuitry at the conclusion of each count. The logic circuitry responds to the counter signal and clock signals coupled thereto to provide an analog pulse width modulated signal corresponding to the digital signal.
