Abstract
A circuit arrangement for multiplying a binary number 6 by an analogue variable 5 comprises a first counter (1) connected to a first pulse generator (3) having a fixed frequency and a second counter (2) connected to a second pulse generator (4) the frequency of which is determined in dependence upon the analogue variable and a circuit (7) for initiating counting by both counters of the pulses produced by the respective pulse generators. Counting by the second counter (2) is terminated after a period determined by the time taken by the first counter (1) to count a number of pulses equal to the binary number 6 which is to be multiplied by the analogue variable 5, the count in the second counter (2) at the termination of counting being equal to the said binary number multiplied by the ratio of the frequency of the second pulse generator (4) to that of the first pulse generator (3).
