Time base correction apparatus
摘要:
A time base correction apparatus includes a feedback loop for performing time base correction of an input signal by detecting a time base error component of the input signal and a filter having an amplitude characteristic approximating an open loop characteristic of the feedback loop for receiving the time base error component. The input signal whose time base error is corrected by the feedback loop is treated by time base correction by a feed forward operation using an output signal of the filter. With this feature, a time base error which was not removed by the feedback loop is further corrected, and an effective time base correction is performed also for high frequencies.
