Multichannel D=A or A=D converter processing method - processing rapid variations in each cycle and slow variations in few only

摘要

A device includes j analog switch groups, an ADC for the signals input via the switches, a DAC for converting the resultant back to analog, and n analog switches for distribution of the signals. Analog store circuitry holds the divided output signals from the n switches. One of the j analog switch groups is switched for each predetermined ADC cycle, and the others for mutually different predetermined cycles. One of the n analog switches is switched for each predetermined DAC cycle, and the others for mutually different predetermined cycles. USE/ADVANTAGE - Process or measuring systems. Allows central unit controlled processing, e.g. for c.r.t. display in cost-effective fashion.
