Abstract

PURPOSE: To convert wide-band analogue signals to digital signals at a high speed with a high conversion precision by supplying successively input analogue signals, which are sampled at a prescribed period, to plural analogue-digital converters.
CONSTITUTION: Analogue signals from the input terminal are sampled by analogue switch 1 and are switched and supplied sucessively to low-speed analogue-digital converters 2 arranged in parallel. In individual converter 2, the sample value of supplied input analogue signals is held in capacitor 4 temperarily and is converted to digital signals. Converted output digital signals of respective converters 2 are supplied to digital switch 3 and are switched at the same period as switching of analogue switch 1, namely, the sampling period and are synthesized in respect to time, thereby constituting overall converted output digital signals.
