Subject: Manages window/filter types better. Disables filter types if the designing algorithm... 
X-Git-Url: https://git.gag.com/?a=commitdiff_plain;h=6fa1fc320b539cac0add465652c0cac170a88db1;p=debian%2Fgnuradio

Manages window/filter types better. Disables filter types if the designing algorithm doesn't support it (no RRC or Gaussian for equiripple filters).
