Patent CA-2146206-A1 (CA)
Title: Analogue-to-digital conversion systems
Inventor: NEWMAN ANTHONY P
IPC: H03M1/12
Filed: 1995-04-03
Abstract: ABSTRACT OF THE DISCLOSURE   In known analogue-to-digital conversion systems with multiple inputs of different kinds, it is usual for each input to have its own signal conditioning circuit, which adds to the cost of the system. In the present invention, the system has a multiplexer that provides sequential output samples of all the inputs via an amplifier to an analogue-to-digital converter. A multiplier between the multiplexer and the amplifier spectrally shifts the signals in one sense. The system also has a second multiplier at the output of the converter, which spectrally shifts the signals in the opposite sense to substantially their original spectral content. The second multiplier also spectrally shifts any noise produced by the amplifier. A digital filter attenuates the noise more than the signal and supplies the different outputs to respective registers. One of the inputs is at a zero level and the equivalent output is subtracted from the other outputs, further reducing noise.
