FBsignal

class pylayers.signal.bsignal.FBsignal(x=array([], dtype=float64), y=array([], dtype=float64), label=[])

Bases: pylayers.signal.bsignal.Bsignal

FBsignal : Base signal in Frequency domain

plot : plot modulus and phase plotri : plot real part and imaginary part plotdB : plot modulus in dB

Methods Summary

plot(**kwargs)	plot FBsignal
plotdB([mask, n, phase])	usage : plotdB()
plotri([nb])	plot real and imaginary part
stem([color])	stem plot
