Claim:
1. A signal processing apparatus for processing a time variant signal, the signal processing apparatus receiving a first input signal and a second input signal, the first input signal being directly used as a first output signal, the signal processing apparatus comprising: a first gain-adjustable amplifier, wherein a gain of the first gain-adjustable amplifier is adjusted according to a first integrated signal, wherein after the first input signal is received by the first gain-adjustable amplifier, a gain-adjusted first input signal is generated by the first gain-adjustable amplifier; a first adder for subtracting the gain-adjusted first input signal from the second input signal, thereby generating a second output signal; and a weighting correlator receiving the first output signal and the second output signal, and generating the first integrated signal, wherein the weighting correlator comprises:
