Actually from the presentation I could get all values but for ¨variable block¨ with ID as taps , i was not sure what value I should choose as it was not clear from the presentation i downloaded. I guess if proper value is given to that block, the flow graph will run. --- On Fri, 2/1/13, Tom Rondeau <[email protected]> wrote: From: Tom Rondeau <[email protected]> Subject: Re: [Discuss-gnuradio] Error in executing filtering example To: "Ghulam Rasool Begh" <[email protected]> Cc: "Gnu Radio" <[email protected]> Date: Friday, February 1, 2013, 8:04 PM On Fri, Feb 1, 2013 at 12:00 AM, Ghulam Rasool Begh <[email protected]> wrote: Hi all, I was simulating filtering.grc example from Digital Modulation Primer using GNU Radio by Tom Rondeau.
