ABSTRACT:
An improved FM receiver is disclosed incorporating improved oscillating limiter circuitry having an electrically tunable bandpass filter which is phase modulated by the baseband signal the phase of which has been advanced in accordance with the formula: ##EQU1## wherein td.sub.1 equals the time delay through the limiter, td.sub.2 equals the time delay through the feedback filter, td.sub.3 equals the time delay through the demodulator and f.sub.n equals the frequency of the respective baseband components.
