| filter-length n | Command |
| This command sets the filter length to n. The filter length is the number of filter coefficients. |
| sampling-frequency f | Command |
| This command sets the sampling frequency to f. All other frequencies in a specification file must belong to the band [0..f/2]. |
| sine-symmetry | Command |
| cosine-symmetry | Command |
The command (sine-symmetry) specifies that the frequency response
H(f) is an odd function, i.e., H(-f) = - H(f). The
command (cosine-symmetry) specifies that the frequency response
H(f) is an even function, i.e., H(f) = H(f). The default
is (cosine-symmetry).
|
| title t | Command |
Set the filter title to t, which is a string. The title is used
for documentation purposes only. If unspecified, the title equals the
string "UNTITLED".
