class	gr_dpll_bb
	Detect the peak of a signalIf a peak is detected, this block outputs a 1, or it outputs 0's. More...
class	gr_feedforward_agc_cc
	Non-causal AGC which computes required gain based on max absolute value over nsamples. More...
class	gr_peak_detector2_fb
	Detect the peak of a signalIf a peak is detected, this block outputs a 1, or it outputs 0's. A separate debug output may be connected, to view the internal EWMA described below. More...
