FM TVRO RECEIVER WITH IMPROVED OSCILLATING LIMITER

摘要

IMPROVED FM RECEIVER 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: wherein td1 equals the time delay through the limiter, td2 equals the time delay through the feedback filter, td3 equals the time delay through the demodulator and fn equals the frequency of the respective baseband components.
