  • $\begingroup$ What type of filter was that? FIR, IIR, Equiripple etc.? $\endgroup$ Commented Sep 23, 2017 at 22:19
  • $\begingroup$ Thanks for the response @Fat32. It was the ready-made "Low pass filter" block which is apparently an FIR filter (ref: www.ece.uvic.ca/~elec350/grc_doc/ar01s12s01.html) $\endgroup$ Commented Sep 25, 2017 at 4:08
  • $\begingroup$ was the length of the filter fixed during the design? $\endgroup$ Commented Sep 25, 2017 at 7:55
  • $\begingroup$ @Fat32 I wasn't sure of that while changing the transition width. In fact the answers helped me understand that decreasing the transition width directly increases the filter length, so I think my filter length wasn't fixed by the ready made LPF block in GNURadio. $\endgroup$ Commented Sep 28, 2017 at 18:51
