Abstract

PURPOSE:To eliminate the transmission distortion included in the FM detection output signal without degradation of selectivity, by adding or subtracting outputs of the first and the second FM detecting circuits. CONSTITUTION:The output signal of the mixing circuit supplied to input terminal 1 is supplied to intermediate frequency filter 2 and level corrector 6 of corrector 2A; and after the output of level corrector 6 is delayed, phase correction of phase shift quantity is performed, and this signal is inputted to one terminal of subtractor 9. Meanwhile, the signal supplied to input termina1 1 is supplied to filter 10 of the same characteristic as the intermediate frequency filter, and the output is supplied to the other input of substractor 9, and the output siganl obtained by detecting the difference signal by FM detecting circuit 12 is added to the output signal of FM detecting circuit 4 to cancel deviation components included in the transmission characteristic of intermediate frequency filter 2, and thus, a good signal without transmission distortion is obtained.
