More often than not, a second opinion alters a plan of care. any help i will be thankful. As you change the kernel, you can also notice the change in the output. Using the strategy of impulse decomposition, systems are described by a signal called the impulse response. A convolution matrix is really just a diagonal band-structure matrix, where every row is all zeros but for the elements around the diagonal, which are identical (but shifted) for every row: the elements of the kernel. I am able to decode hidden bits using cepstral correlation . %here calculating the delay points after which echo will be added, this one is a little detailed but works like a charm, %Number of additional points needed for delay, %if delay is not equal to zero output size will be N greater, %first N points will only contain original sound, %points ranging from N+1 to sz will contain original Sound +amplified sound of a previous time, %Last N points will only contain amplified data points, %first sz points will get only original signal data, %points ranging from sz+1 to N will contain nothing, %points after N will contain amplified signal only, %scaling if values fall outside the range [-1,1].
