[Discuss-gnuradio] designing filters: remez?

[Patrick Strasser]

Hello!

I thought about a graphical filter designer (probably to be integrated 
with GRC). I read up about the window method and the Remez method. I 
found both in GNU Radio code, but the examples only use the window 
method functions. Is there something bad about designing filters with 
the Remez method? I thought it would be clever to constraint the filter 
to a number of coefficients, as this parameter is most important for 
processing speed.

Moreover, what would bring faster results, a designer using the window 
method or one with the remez method?
