design_fir_srrc1
Square-root raised cosine filter design (1).
Namespace: dsp::filter
Prototype
Vecf design_fir_srrc1(int n, float β, float osf, char nrm='s')
Parameters
| n | Filter order. |
| β | Roll-off factor. |
| osf | Oversampling factor ( \(\frac{f_e}{f_{symb}}\)). |
| nrm | Type of normalization for the coefficients ('s' for sum = 1, 'e' for sum of squares = 1). |
Description
This function is equivalent to design_fir_srrc(), only instead of the cut-off frequency \(f_c\), it is the over-sampling factor which is specified ( \(\textrm{OSF} = \frac{1}{2 f_c}\)).
