Abstract:
To easily adjust the gain of digital signals outputted from a multi-channel A/D converter.
Analog signals are converted into the digital signals by ΔΣmodulators 3a and 3b and digital decimation filters 4a and 4b, a prescribed coefficient is multiplied with the digital signals outputted from the digital decimation filters 4a and 4b in multipliers 5a and 5b and thus, the output level of the digital signals outputted from this multi-channel A/D converter is optimally adjusted.
