Abstract

768,561. Television. ULTRA ELECTRIC, Ltd. Feb. 22, 1955 [March 4, 1954], No. 6367/54. Drawings to Specification. Class 40 (3). [Also in Group XL (c)] In a television receiver, sound interference is prevented by a parallel resonant circuit, tuned to approximately the difference frequency, 3.5 Mc/s., between the sound and vision carriers in series between the video detector and the control grid of the video amplifier and such that it forms, with the input capacitance of the latter, a series circuit resonant at a frequency which extends the frequency response of the video amplifier up to 3 Mc/s.
