Abstract

694,725. Television. ELECTRIC & MUSI CAL INDUSTRIES, Ltd. May 7, 1951 [May 6, 1950], No. 11260/50. Class 40 (iii). [Also in Group XL (c)] Apparatus for generating a composite line- and-frame synchronizing waveform in a non- interlaced television system comprises means for generating pulse waveforms 33 and 34 of the frame and line-scanning frequencies respectively means utilizing the line-frequency pulses during the frame-frequency pulses to produce " slots " 35 in these latter pulses and means for combining the resultant signal with the remainder of the line-frequency pulses to produce the composite synchronizing signal.
