Equalizer's Coefficients (FIR Type)
Click "Design->Response" to design and draw. Then click "Coeffs" to get coefficients. Adjusting sliders changes its characteristics. The equalizer is FIR type and the tap count is up to 99. Frequencies are normalized. i.e. Sampling Frequency is 1.0, Nyquist Frequency is 0.5.

Here is a mathematical model of n th order FIR filter. "D" is a unit delay element. "n" is called "tap count".
