From 3751671d1b596113e441ca326280bdcc94fdcc6f Mon Sep 17 00:00:00 2001 From: Tom Rondeau Date: Tue, 28 Dec 2010 12:48:18 -0500 Subject: PFB channelizer can be specified without external taps. Uses optfir to generate an internal filter to cover the channel bandwidth; user can specify the attenuation of this filter if desired. --- gnuradio-examples/python/pfb/channelize.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'gnuradio-examples/python/pfb') diff --git a/gnuradio-examples/python/pfb/channelize.py b/gnuradio-examples/python/pfb/channelize.py index 27d87e558..f845c05c6 100755 --- a/gnuradio-examples/python/pfb/channelize.py +++ b/gnuradio-examples/python/pfb/channelize.py @@ -36,7 +36,7 @@ class pfb_top_block(gr.top_block): # Create a set of taps for the PFB channelizer self._taps = gr.firdes.low_pass_2(1, self._fs, 475.50, 50, - attenuation_dB=10, window=gr.firdes.WIN_BLACKMAN_hARRIS) + attenuation_dB=100, window=gr.firdes.WIN_BLACKMAN_hARRIS) # Calculate the number of taps per channel for our own information tpc = scipy.ceil(float(len(self._taps)) / float(self._M)) -- cgit
