设计滤波器时，可以输入相应要计算的值，自动计算频率，电容，电阻等。-Design filter, you can enter a value corresponding to the calculated automatically calculate the frequency, capacitance, resistance and so on.

1. To study the effects of quantization noise in digital signal processing systems2. To investigate the effects of quantized filter coefficients on frequency response3.To compare the effects of quantization on different implementation structures, e.g
