Variations of muting characteristics with a resistor
connected between pin 5 and GND varied.
(Adjustment of the maximum muting attenuation)
Sample Application Circuit 2
High Frequency Section of Car Radio and Car Stereo with Noise Canceller and FM Stereo Multiplexer
Almost all noise under a medium and lower input signal strength can be rejected by processing the muting characteristic of the
LA1140, the stereo noise control (SNC) characteristic and the high cut control characteristic of the LA3370. These examples are
as follows:
