[Discuss-gnuradio] block that does simple tone detection

2010-02-26 Thread Affan Syed
Hi all, I have been building a simple block that can detect energy at a particular frequency, i.e. a tone detection block. The signal processing seemed simple enough for me, so I directly coded it. Essentially my tone_sink takes in float point samples of the input signal (passed through a
