Assuming all 'blah' have same number of bits, would that not be:
(number of bits per 'blah')*N ?

Hi all,
In the case I don't know the sampling frequency. Specifically, I only
given a discrete function:
f[n]= blah blah..... with length N.
I use wavelet based compression method:
Decompose the signal into N wavelet coefficients, quantize and then
encode these coefficients with M bits for each coefficient.
Now to report the algorithm, I need to submit it's RATE. In the case,
what formula is for RATE calculation?
I guess it will be Size of compressed data / size of original data
I know the size of my compressed data: it is the number of bits *
number of coefficients= M*N bits
But what is the size of my original data :(f(n))??
Thanks
