IIR Filter Design ExampleLet's design an IIR filter putting parameters like LPF, Number of IIRs=2, Fc=200, Sampling Frequency=1000 The frequency response is drawn like this. In order to implement it into hardware, you need to quantize coefficients by 16 bits. The quantized coefficients are listed up. Let's generate VHDL codes!! The bit length of input data is 12 in this case. The VHDL code has been listed up!! Let's save it by clicking "Save/Load". Next |
