Abstract
A filter circuit comprises a 1-bit quantizer, a first moving average type of filter having an N-dimensional 1-bit delay element operating in synchronism to a clock of a first sampling frequency, a thinning circuit for thinning an output from the first moving average type of filter in synchronism to a clock of a second sampling frequency, and a second moving average type of filter having an M-order q-bit delay element operating in synchronism to a clock of a second sampling frequency, wherein the thinning circuit removes anti-alias elements in the second moving average type of filter.
