5-6 Sound processing
5-6-1 Analogue sound IF - input section
The input pins and ANA_IN- offer the possibility to connect sound IF sources to the MSP 341xD. 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.
5-6-2 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.
5-6-3 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.
