ABSTRACT:
A frequency demodulation device having a circuit for limiting the amplitude of a frequency modulated signal, an integration circuit and a low pass filter. Two successive output signals from the amplitude limiting circuits are integrated in the integrating circuit in accordance with first and second predetermined time constants.
The signal is then fed to the filter which extracts the mean value from the output signal of the integrating circuit. This mean value is proportional to the modulated wave frequency and thus determines that frequency.
