5.7 SOUND PROCESSING
5.7.1 ANALOGUE SOUND IF - INPUT SECTION
The input pins ANA_IN1+ and ANA_IN- offer the possibility to connect sound IF sources to the
MSP 341xG. The analogue-to-digital conversion of the preselected sound IF signal is done by an
A/D converter, whose output is used to control an analogue automatic gain circuit (AGC),
providing an optimal level for a wide range of input levels.
5.7.2 QUADRATURE MIXERS
The digital input coming from the integrated A/D converter may contain audio information at a
frequency range of theoretically 0 to 9 MHz corresponding to the selected standards. By means
of two programmable quadrature mixers, two different audio sources ; for example, NICAM and
FM-mono, may be shifted into baseband position.
5.7.3 PHASE AND AM DISCRIMINATION
The filtered sound IF signals are demodulated by means of the phase and amplitude
discriminator block. On the output, the phase and amplitude is available for further processing.
AM signals are derived from the amplitude information, whereas the phase information serves for
FM and NICAM demodulation.
