TUA 4307
Wireless Components
Specification, September 1999
The value above are calculated as follows:
Total audio level FM:
AF output voltage x stereodecoder gain
Total audio level AM:
AF output voltage x stereodecoder gain
Stereodecoder gain = AF output voltage / V63 = 600 mVrms Input voltage decoder.
The automatic test values are including the additional spread of a high volume automatic testfloor tolerances.
