ABSTRACT:
There is an apparatus for generating a velocity error signal for use in a time base corrector. This apparatus comprises: an A/D converter that converts a velocity error to a digital signal that is fed to a summing circuit to convert it to a phase shift amount. A zero value interpolation circuit multiplies the sampling frequency of the phase shift amount with an integer and a digital low-pass filter interpolates an output signal of the interpolation circuit. A differentiating circuit to convert an interpolated phase shift amount of an output signal of the LPF to a phase difference and a D/A converter 9 converts the digital phase difference data to an analog signal. With this apparatus, the velocity error can be accurately corrected.
