Abstract

PURPOSE:To digitally demodulate an FM signal by setting a prescribed formula between the occupied band width of an IF and a sampling frequency. CONSTITUTION:An IF signal from an analog circuit part 1 is A/D-converted 8 with a sampling frequency fs and next, FM-detected 9. The detecting circuit 9 is provided with a Hilbert transform circuit, and ATAN circuit and a difference circuit. The detected digital composite signal is demodulated with a multiplexing circuit 18. When the occupied band width of the IF signal is fw, the setting to satisfy the relation of 2fw<<fs at the section of the frequency fs is executed.
