Low Pass Filter
Figure 13 shows the five possible corner frequencies of the low pass filter:
Figure 13. Low Pass Corner Frequencies
Anti-Radiation-Filter
An Anti-Radiation-Filter is implemented to suppress the radiation at the SC-clock-frequency and its har-
monics. This radiation is only present if the stereo decoder is selected and/or SC-Filters are active
(<>0dB). If not, the filter can be switched off in order to optimize the noise-performance.
Speaker Attenuator
The speaker-attenuators have exactly the same control range like the Volume-stage. Every stereo speak-
er stage has an implemented independently I
section mute capability of AP).
