    How to shorten a signal (in terms of time)?

    Re: shortening of signal correlation is some like convolution, is there requirement that the two sequence in convolution must be equal size?

    How to shorten a signal (in terms of time)?

    Re: shortening of signal 260 points convoluted with 16 points kernel get the 260+16-1=275 point result. what's your reason to discard other points for keeping the same size of input?

    [SOLVED] Suggestion in PCB designing.

    although there are so many difference between each, you need to learn and master just one. i think ORCAD/ALLEGRO is better, because it's all manual in each stage, which means that you know what you are doing.

    DTFS, DTFT and DFT: Whats the difference

    in my view (1) DTFS and DFT refer to the same thing (the spectrum of a periodic discrete-time sequence), since the properties of DFT are all the same as DTFS's. the only difference is DFT is explained in one period, and "circular" is used. (2) DTFT and DTFS are different, since one is for...
