Quality detector
The TDA7406 offers a quality detector output which gives a voltage representing the FM-
reception conditions. To calculate this voltage the MPX-noise and the multipath-detector
output are summed according to the following formula:
The noise-signal is the PEAK-signal without additional influences (see noiseblanker
description). The factor 'a' can by programmed from 0.7 to 1.15. The output is a low
impedance output able to drive external circuitry as well as simply fed to an AD-converter for
RDS applications.
