Abstract

PURPOSE:To simplify the constitution of a detecting device by operating an arc tangent from a digitally converted FM signal and the same FM signal through the delaying circuit of a necessary delaying time and executing the detecting processing. CONSTITUTION:A digital FM signal X from an input terminal 1 and the approximately 1/4 delayed digital FM signal Y of the synchronization of a carrier signal by a delaying circuit 11 are supplied and an arc tangent arithmetic circuit 3 calculates and outputs an arc tangent (X/Y). The output and a one-period- delayed output through a delaying circuit 4 are processed with output of a coefficient circuit 7 and a subtracter circuit 6 through a subtracter circuit 5, and becomes a detecting output to remove a direct current component. By using the delaying circuit 11, a Hilbert converting circuit is eliminated and the constitution of an FM detecting device can be simplified.
