ABSTRACT:
A digital-to-analog converter using a combined pulse rate and pulse width modulation of an output signal of a circuit for providing a digital signal to be converted to a periodically occurring series of digital comparison signals to be obtained by a proper choice of a particular series. The digital-to-analog converter has a very small error which, due to its low temperature sensitivity, is particularly suitable for tuning circuits of television receivers.
