运用于时变信号的信号处理装置;SIGNAL PROCESSING APPARATUS FOR TIME VARIANT SIGNAL

摘要

一种运用于时变信号的信号处理装置，包括：一加法器，接收一第一输入信号以及一积分信号，并产生一第一输出信号，其中该第一输出信号等于该第一输入信号与该积分信号做减法运算；以及，一权重积分器，接收该第一输出信号并产生该积分信号；其中，该权重积分器更包括：一权重函数产生器，接收该第一输出信号，并在该第一输出信号通过一零交越点附近时产生一权重函数；一乘法器，将该权重函数乘以该第一输出信号；以及一累加器，连接至该乘法器，并累加该权重函数乘以该第一输出信号的结果，并据以产生该积分信号。; and a weighting integrator capable of generating the integrated signal in response to the first output signal. Furthermore, the weighting integrator includes a weighting function generator capable of generating a weighting function when the first output signal crosses a zero cross point; a multiplier capable of multiplying the weighting function and the first output signal; and a accumulator connected to the multiplier capable of accumulating a result of multiplying the weighting function and the first output signal and generating the integrated signal accordingly.
