Abstract

1299510 Analogue-to-digital coding STANDARD TELEPHONES & CABLES Ltd 13 Nov 1970 [18 Nov 1969] 54099/70 Heading G4H The effect of cross talk and parasitic signals in the invention described in Specification 999,280 is reduced by shifting signal levels on the calibration channel and the normal channels by half a quantization step. A time division multiplexing arrangement using relays or field effect transistors is described.
