【Abstract】 As a basic module of digital signal processing,FIR digital filter is widely used in modern electronic systems for its good linearity.Combined with MATLAB software tool,FIR filter convolution algorithm has been described and simulated on the basis of Verilog HDL and Modelsim.It is proved that the simulation results meet the amplitude-frequency characteristic in design requirements very well.更多还原
