Abstract

An analog to digital converter apparatus arranged to convert a plurality C (=4) of different input signals to digital representations thereof. The apparatus comprises a multiplexer arranged sequentially to couple each of the 4 input signals to a fast a-to-d converter (such as a successive approximations converter) at a rate such that each input signal is coupled N (=8) times in a period M (=20 m secs) of an a.c. series mode interfering signal (at 50 Hz) and at equal time intervals M/N (20/8=2.5 m secs). The N (=8) digital values of each input signal are averaged to provide at the end of a conversion period a digital value for each of the 4 input signals (C) which is the mean magnitude of the signal during the 20 m sec period (M).
