Abstract

The present invention relates to an electronic device for analog-to-digital conversion including a sigma-delta modulator (SD), a digital filter (FIL) for digital post processing of the output signal of the sigma-deltamodulator (SD), a multiplexer (MUX) for switching the input (INSD) of the sigma-delta modulator between a first input signal (IN1) and a second input signal (IN2), amemory (MEM) adapted to hold the register content of the digital filter relating to the first input signal while the second input signal (IN2) is processed in the digital filter, and a controller (CNTL) to retrieve the register contents from thememory (MEM) when processing of the first input signal (IN1) in the digital filter is resumed.
