ABSTRACT:
A frequency modulation detector is constructed of a plurality of monostable multivibrators, an analog and a low-pass filter. One of the plurality of monostable multivibrators generates a first train of pulses of predetermined pulse width in response to the rising edges of an input signal, while another of the plurality of monostable multivibrators generates a second train of pulses of the same predetermined pulse width in response to the falling edges of the input signal. The first and second trains of pulses are applied to the analog adder, an output signal of which is applied to an input terminal of the low-pass filter. An FM detection output signal is provided from an output terminal of the low-pass filter. By this means the high-frequency components and carrier components of the input to be contained in the FM detection output signal are substantially reduced.
