ABSTRACT:
In order to convert a basic frequency by an odd integer K = 2n.+-.1, a square wave of that basic frequency is fed alternately over a noninverting and an inverting branch of a switching circuit to a pulse counter working into a decoder which emits a resetting pulse for the counter on every n.sup.th cycle. A flip-flop alternately set and reset by successive setting pulses feeds back a control signal to the switching circuit for a periodic reversal of the polarity of the incoming square wave either in the middle of the n.sup.th cycle, for K = 2n-1, or after a half-cycle delay from the end of the n.sup.th cycle, for K = 2n+1.
