Re: [Discuss-gnuradio] gr_firdes cutoff frequency

Hi Songsong, the cutoff frequency is relative to the given sampling rate, whatever that is. The firdes stuff doesn't know about the "true" sampling rate. It's not uncommon to set the sampling rate to 1 and then have cutoff somewhere in between 0 and 1. MB On Mon, Dec 12, 2011 at 02:53:07PM +090

[Discuss-gnuradio] gr_firdes cutoff frequency

I'm looking benchmark program and now found use of gr.firdes.low_pass: chan_coeffs = gr.firdes.low_pass (1.0, # gain sw_decim * self.samples_per_symbol(), # sampling rate 1.0,
