Abstract

PURPOSE:To make a stable operation possible by subtracting distortion signals from a detection output means. CONSTITUTION:Interferance FM signal C0(t) which comes from input terminal 1 is applied to FM detection circuit 2 and AGC circuit 3. The output of AGC circuit 3 made into a fixed value has a negative envelope detected by envelope detection circuit 5, and AC components are applied to function circuit 7. The signal to which a hyperbolic characteristic is given by function circuit 7 is multiplied by the signal of operation circuit 12 in an analogue multiplier and is applied to operation circuit 4. The output from operation circuit which has a distortion signal removed is delayed by a time equal to the time delay of plural reflection waves in delay circuit 10 by selecting the delay time by selector switches S1-SN and is applied to operation circuit 13. Then, signals which have distortion signals removed are outputted from terminal 9.
