Notes to the characteristics
1. V
2. Without de-emphasis capacitors with respect to nominal gain.
3. In dual mode: A (B)-signal into B (A) channel; in stereo mode: R-signal into left channel; L-signal = 0.
4. Tuner input signal, measured with PCALH reference front end (
5. Bandwidth of the pilot BP-filter B
6. Identification window is defined as twice the pull-in frequency range (lower plus upper side) of identification PLL
7. The maximal total system identification time on is equal to t
8. The maximal total system identification time off is equal to t
