Abstract :
A novel audio LSI for VHS VCRs in which the time-base-error corrector and four digital FM demodulators are integrated using digital signal-processing technology has been developed. Switching noise reduced more than 10 dB compared with the conventional system, and good high-fidelity sound for VHS VCRs was achieved
