US Patent:

39449432, Mar 16, 1976

Filed:

Nov 29, 1974

Appl. No.:

5/528337

Inventors:

Frederick Frank Reed - El Paso TX

Assignee:

GTE Sylvania Incorporated - Stamford CT

International Classification:

H03F 136

US Classification:

330109

Abstract:

A broadband amplifier with a negative feedback circuit having a variable resistance means and first and second parallel resistor-inductor combinations for slope control is shown. The variable resistance means establishes the overall frequency response and can be electronically varied to provide automatic gain control. The first and second parallel resistor-inductor combinations provide compensation for deviations from the desired frequency response over respective first and second frequency ranges.

Appl. No.:

5/868035

Frederick F. Reed - El Paso TX

Assignee:

GTE Sylvania Incorporated - Stamford CT

International Classification:

H04N 144

US Classification:

358118

Abstract:

A circuit for transmitting a jamming signal for disruption of a television signal transmitted along a cable or other guided path toward a television receiver, the circuit having a first oscillator means providing an audio frequency signal which is used to frequency modulate a second oscillator means between the signal video and audio carrier frequencies inclusively and having a third oscillator means providing square-wave horizontal-sweep-frequency signal which is used with an amplitude-modulating means for amplitude-modulating the output of the second oscillator means to produce a jamming signal for directional coupling into the guided path for the purpose disrupting both audio and video content of the television signal.
