The gr.pwr_squelch block is a new implementation of power thresholded squelch I did last year, but did it in a way that can share code with other new and future squelch implementations, like gr.ctcss_squelch. Algorithmically, it uses the same exponential average filter on the squared magnitude of the incoming sample stream, so it that sense, it is redundant. However, it also has additional functionality (ramping, skipping samples vs. emitting zeros) not present in gr.simple_squelch. To not break existing code in the wild, the original squelch has been left in. I suppose we could officially deprecate it, and remove it in a future release, but it's actually easier to use if you don't need the fancier stuff in pwr_squelch. -- Johnathan Corgan Corgan Enterprises LLC http://corganenterprises.com _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
