SIGNAL PROCESSING APPARATUS FOR PROCESSING TIME VARIANT SIGNAL

摘要

A signal processing apparatus includes an adder and a weighting integrator. The adder receives a first input signal and an integrated signal, and generates a first output signal. The first output signal is obtained by subtracting the integrated signal from the first input signal. The weighting integrator receives the first output signal, and generates the integrated signal. The weighting integrator includes a weighting function generator, a multiplier, and an accumulator. The weighting function generator receives the first output signal. When the first output signal crosses a zero crossing point, the weighting function generator generates a weighting function. The multiplier performs a multiplication on the weighting function and the first output signal. The accumulator is connected to the multiplier for accumulating the product of the weighting function and the first output signal, thereby generating the integrated signal.
