As the word indicates, a filter separates a desired signal from unwanted disturbances. For example, when the users want to remove a disturbance such as noise from an audio signal, the authors design an appropriate filter that passes only the desires signal. The paper introduces the basic structure and the principles of the finite impulse response digital filter, and gives an efficient FIR filter design on FPGA .Use Matlab FDATOOL to determine filter coefficients and designed to constant coefficient FIR filter by VHDL, use of ISE 10.1 to simulate the performance of filter using two different techniques.
