Document Type and Number:

Japanese Patent JP2850643

Kind Code:

B2

Abstract:

Different from typical signal processing which employs a feedback control, by adopting a demodulating circuit employing AFC, which is not affected by a comb filter, the response characteristic against jitter is improved and a down converted chrominance signal can be demodulated with a good accuracy. therefore, the noise rejection effect by a comb filter is improved, the detecting accuracy of the residual phase error is also improved, and the S/N ratio of the phase is improved by combining feedforward APC compensation with a velocity error, and this results in a much improved picture quality.
