V/20 dB
Attack and decay time for mute voltage.
I
Time constant for mono/stereo blend voltage. The mono/stereo blend voltage is generated as a function of FM IF
voltage, multipath level, noise and position of Tswitch.
I
m
Time constant for high-cut control voltage (SDR). The high-cut control voltage is generated as a function of FM IF
voltage, multipath level, noise and position of Tswitch.
