Quantisation Noise (QN) to WV

This function compute the Haar WV of a Quantisation Noise (QN) process

qn_to_wv(q2, tau)

Arguments

q2	A `double` corresponding to variance of drift
tau	A `vec` containing the scales e.g. $2^{\tau}$

A vec containing the wavelet variance of the QN.

The Quantization Noise (QN) process has a Haar Wavelet Variance given by: $$\nu _j^2\left( {{Q^2}} \right) = \frac{{6{Q^2}}}{{\tau _j^2}}$$

q2	A `double` corresponding to variance of drift
tau	A `vec` containing the scales e.g. \(2^{\tau}\)
