ButterworthReturn base filter coefficients of Butterworth filter (= low pass filter with w_cut = 1 rad/s) |
 |
Syntax
(cr, c0, c1) = Butterworth(order, normalized)
Inputs (2)
| order |
Type: Integer Description: Order of filter |
|---|---|
| normalized |
Default Value: true Type: Boolean Description: = true, if amplitude at f_cut = -3db, otherwise unmodified filter |
Outputs (3)
| cr |
Type: Real[mod(order, 2)] Description: Coefficient of real pole |
|---|---|
| c0 |
Type: Real[integer(order / 2)] Description: Coefficients of s^0 term if conjugate complex pole |
| c1 |
Type: Real[integer(order / 2)] Description: Coefficients of s^1 term if conjugate complex pole |
