Hello I am implementing an FIR filter in Verilog, using the DE2 board. For some reason the output out of the speakers is full of static, although it does appear to filter out some frequencies. Here is the code for the FIR: // Local wires. wire read_ready, write_ready, read, write;...
Parks-McClellan: Parks-McClellan 方法( MATLAB里用Remez)是设计FIR滤波器中可能是使用最光的.method (inaccurately called "Remez" by Matlab) is probably the most widely used FIR filter design method. It is an iteration algorithm that accepts filter specifications in terms of passband and stopband fre...

It is found that the choice of address-length M=4 yields the best of area- delaypower-efficient realizations of the FIR filter for various filter orders. Moreover, the proposed FPGA implementation is found to involve significantly less area-delay complexity compared with the existing DA-based ...
