scipy.signal.normalize¶
- scipy.signal.normalize(b, a)[source]¶
Normalize numerator/denominator of a continuous-time transfer function.
If values of b are too close to 0, they are removed. In that case, a BadCoefficients warning is emitted.
Parameters: b: array_like
Numerator of the transfer function. Can be a 2d array to normalize multiple transfer functions.
a: array_like
Denominator of the transfer function. At most 1d.
Returns: num: array
The numerator of the normalized transfer function. At least a 1d array. A 2d-array if the input num is a 2d array.
den: 1d-array
The denominator of the normalized transfer function.
Notes
Coefficients for both the numerator and denominator should be specified in descending exponent order (e.g., s^2 + 3s + 5 would be represented as [1, 3, 5]).
