The LA2110 has the capability to effectively remove external noise (pulse noise) caused by engine, etc. and is used in

conjunction with a PLL FM multiplex stereo demodulator (such as LA3375) with pilot signal canceller.

• Low distortion factor : THD = 0.02%, 300mV.

• Good space facator due to single end package.

• Variable input type noise AGC system. This system widens the noise detector’s dynamic range, so that pulse noise can be

... Theory of LA2110 Noise Canceller Composite signal output In order to simplify the operation theory, the composite signal component is given only as a low frequency signal and a pilot cancel signal has the same phase, same amplitude as the pilot signal in the composite signal. Since the output voltage is the differential voltage of the plus and minus input of the subtraction circuit equal to the voltage between the memory capacitor terminals ...
