  • Pulse generator for television for generating at least one pulse series having pulses of different duration and repetition period
    Patent number: 3935387
    Abstract: A TV pulse generator for generating television synchronizing and blanking signals and a chrominance subcarrier gating signal. The switchable generator is formed with a clock pulse generator having a frequency which, for the CCIR and the RTMA standards, is 80 times the line frequency. In addition to auxiliary pulses of field frequency, circuits of frequency dividers formed with JK flip-flops and pulse generators also generate auxiliary pulses of line frequency and of double the line frequency. The edges in the synchronizing and blanking signals and in the PAL or NTSC chrominance subcarrier gating signal generated by signal generators are accurately determined by trigger signals derived from the clock pulses.
