no sir. not with dB. this is why we use
dB = 20 * log10(amplitude)
and
dB = 10 * log10(power)
r b-j
I see, so it is 6 dB/octave (brown).
The FT of (1/3)*(1-P)^|k| is (1/3)*(1-Q^2)/(1-2Qcos(w) + Q^2), where Q =
(1-P).
Looks like you were thinking of the expression for the transform of the
one-sided decaying signal u[k]*(1-P)^k?
E
Yes, exactly. Thanks for sorting that out.
