Abstract
To obtain timing signals which continue essentially in phase even in the case of signal drop-out, a timing signal is supplied to a phase comparator which is also connected to a variable oscillator. Low-frequency output of the comparator is supplied to circuitry which, in the case of signal drop-out, initially retains a most recently encountered frequency and which then gradually shifts to a frequency which is the average of recent frequencies.
