Abstract

730,758. Automatic frequency control systems. RADIO CORPORATION OF AMERICA. Aug. 7, 1953 [Aug. 23, 1952], No. 21862/53. Drawings to Specification. Class 38 (4). [Also in Groups XL (b) and XL (c)] An automatic frequency controlling system comprising a known arrangement of phase detector and reactance controlled oscillator is employed in a colour television transmitter to maintain a fixed frequency difference between the sound carrier and the colour sub-carrier.
