ABSTRACT:
An I/Q demodulator optimized with a minimum amount of hardware. First and second multiplexers generate I and Q signals with respect to an input data signal; and first and second 2-decimation units decimate the I and Q signals generated by the first and second multiplexers, to output effective I and Q signals. A filtering unit filters the effective I and Q signals. As a result, a size of the hardware is reduced, and an operation frequency of the filter is reduced.
