All above mentioned
units use separate ICs for signal processing: from the laser to the
- SAA7010 Demodulator
(separates
clock and data) to the
- SAA7020 Error
correction
(error
detection and correction) to the
- SAA7000
Concealment and Interpolation
(separates L +
R, audio correction) to the
- SAA7030
Digital Filter
(Oversampler)
to the
- TDA1540 DAC Digital
Analog Converter
(one per
channel) and finally into the
analogue output stage
(NE5532).
