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
