ABSTRACT:
A digital demodulator includes: a local oscillator for generating a predetermined frequency signal; a mixer for mixing an intermediate frequency (IF) signal with a local oscillation frequency signal output by the local oscillator; an A/D converter for converting a signal output by the mixer into a digital signal; an I and Q signal generator for producing I and Q signals from an output of the A/D converter; and a compensation unit for compensating the signals I and Q for phase errors.
