Abstract

A single-chip LSI has been developed to decode audio signals which are multiplexed into MUSE (multiple sub-Nyquist sampling encoding) signals for transmitting HDTV (high-definition television) signals. Because the LSI requires just a few peripheral parts (such as two RAMs and one voltage-controlled oscillator circuit), use of the LSI can reduce the size of the MUSE audio signal decoding digital unit. In addition, problems such as noise generated in the conventional units when the MUSE signals are stopped can be greatly reduced. Thus, the LSI is suitable not only for satellite broadcast receiving but also for the playback of MUSE video discs and other package media
