Phase locking system for television signals using digital memory techniques |
摘要 |
An electronic system phase locks one or more input television signals to a signal of reference frequency and phase. The incoming signal is sampled at a first clock rate and phase, pulse code modulated, and stored in memory. The stored video information is then read out from memory under control of a second and independent clock which corresponds in its essential timing aspects to the reference signal.
