Abstract

PURPOSE: To generate more accurate continuous sub-carriers by detecting a speed error from a phase error in each horizontal scanning interval and by generating a speed-error correcting signal.
CONSTITUTION: As for NTSC input signals, a burst signal is wave-form-shaped by zero-cross pulse generators 2 and 4 and zero-cross pulses (b) and (c) are extracted, which have phase errors Δϕ1 and Δϕ2, so that speed phase error voltages ΔV1 and ΔV2 will be henerated from sample holding circuit 5. Those voltages are detected and error voltages of each single horizontal scanning are extracted and applied to correcting-valtage generator 7, where the peak value is integrated. Then, variable delay element 9 which allows local sub-carriers to pass through is controlled by the sum output of this value and the output of circuit 5, so that continuous waves 10 synchronizing with remote sub-carriers can be obtained.
