Abstract
A frequency oscillator for generating a square wave output pulse train is connected via a frequency divider circuit to a binary shift register which is designed as a divide-by-n counter with m counter stages, wherein m=n/2. Each stage is associated with an output. A resistor network is composed of m rated resistors each of which resistors is connected to a respective register output and in common to an input of a low-pass filter network forming the output circuit. The rating of the resistors is such that an k-th resistor associated with the k-th output of the shift register has the value ##EQU1## wherein R is a reference resistance value;
