CLOCK GENERATOR FOR VIDEO SIGNAL PROCESSING |
摘要 |
A clock generator is provided which demodulates the burst subcarrier portion of a video signal containing time base errors. The demodulation is with respect to an external subcarrier reference signal so that the demodulator output represents an accurate vector summation of the instantaneous phase and amplitude difference of the incoming video signal relative to the external reference. The demodulator output is utilized to remodulate the external reference signal to provide a rephased subcarrier reference signal which is frequency multiplied and waveshaped to produce a clock signal which is synchronized to the incoming video signal. |
