Combined pulse rate and pulse width modulation of an output signal of a circuit for comprising a digital signal to be converted with a periodically occurring series of digital comparison signals can be obtained by a proper choice of that series. By means of the said circuit a digital-to-analogue converter can be obtained having a very small error which, owing to its low temperature sensitivity, is particularly suitable for use in tuning circuits, of, for example, television receivers. |
