can anybody tell me how to manipulate data from sources present in signal processing in MATLAB. i want to use dspsrcs4 from MATLAB for real time application.

i am doing project on watermarking using spread spectrum. watermark signal is text signal. to encode this binary signal i am using BCH encoder. this encoded watermark is supposed to converted into level 1 and -1 corresponding to 1 and 0. but after encoding this watermark signal can not be...
can i get code for audio watermarking for different encoder?

I can work it out with the help of my guide specialiasing on Error correcting code? but I am working on watermarking encoder where she has no idea about...
Sampling is 1 st step of convering analog to digital.sampling theorem is described by nyquist in order to fathfully recoveir analog signal from digital.sampling is taking sample of continuos signal at discrete time or regualr interval of time.but this interval should be chosen carefully.
If u...
u can perceive time domain signal. like speech signal its amplitude vary with respect to time.in time domain u try tro give information of amplitude of signal with respect to its time.to understand frequency domain u must know what is frequency component of signal. Frequency component of signal...
If i want to stretch mute period in speech signal in time domain how it can be done ? please tell me if it is possible in frequency domain? is stretching time period same as time shifting?so instead of working with time domain signal, can i work with frequency domain signal? Please reply
