Abstract
PURPOSE:To attain digital signal processing even when number of analog input signal systems is increased, by adding a digital signal of M-set of corresponding A/D converters or a digital signal of (N-M) sets of A/D converters stored in a memory to M-set of digital filters. CONSTITUTION:When the output of a tri-state buffer 10 such as a multiplexer 4 is set to a high impedance, the multiplexer 4 is disconnected from a data bus 5 and the digital filter 3 and the memory 6 are connected via a data bus 5. In this state, the output signal of the A/D converter 22 stored in the memory 6 is outputted sequentially to the digital filter 3 to apply signal processing. Thus, the number of digital filters is decreased more than the number of A/D converters and the memory capacity is reduced more than the constitution that the output signal of each A/D converter is stored in the memory and then the signal stored in the memory is fed to the digital filter.
