摘要： A receiver device for a satellite communication system capable of transmitting in either of two modes detects which transmission mode is currently in effect and adjusts its signal processing and output stages accordingly. The transmission may be recognized by reference to either the encoded information or the electromagnetic medium itself of the received electromagnetic transmissions. In one mode, only audio signals and related information are broadcast in FM form whereas in the other mode, a video image signal is also included, while a subcarrier signal is modulated by an audio and/or a data signal. The receiver system checks either the sub-carrier signal or video synchronization signals in the incoming transmissions to determine the transmission mode. The receiver may also be forced to a predetermined mode upon power-up to prevent spurious mode-selection errors.

摘要： A tuner for use with a television receiver includes a mixer receiving and mixing radio frequency and local oscillator signals and a low-pass peaking circuit for preferentially coupling the intermediate frequency from the mixer to an intermediate frequency amplifier. A capacitor in parallel with a series combination of an inductor and a capacitor in the peaking circuit forms a trap circuit for blocking spurious high-frequency signals from the intermediate frequency amplifier. An emitter follower between the mixer and the intermediate frequency amplifier may be included within the parallel connection.
