By re-convolution formula, the product in the time domain can be expressed as the periodic convolution in the frequency domain relationship, you can get the design fir filter's frequency response

Complex convolution formula in accordance with, in the domain of product relations can be expressed as a cyclic convolution in the frequency domain, you can have the design of FIR filter frequency response

According to replies the convolution formula, may express in the time domain product relations in the frequency range periodic convolution relations, the FIR filter frequency response which then designs

In accordance with longer Convolve formula, the time when the product relationships can be expressed in the domain into the frequency domain, the cyclical Convolve relations FIR filters can be designed by the frequency response

Complex convolution formula in accordance with, in the domain of product relations can be expressed as a cyclic convolution in the frequency domain, you can have the design of FIR filter frequency response
