  • Choi-Williams

    Hello in biomch-l Land!

    In order to determine electrical activation parameters from dynamic
    contractions I wanted to utilise FFT procedures. As I learned from
    literature studies this is not the appropriate way as the signal of the
    EMG is not stationary. The procedure of choice is supposed to be the so
    called Choi-Williams algorithm. Who of you can give me some more details
    on that topic and the Choi-Williams in particular. Where can I find the
    algotrithm and background information about the conditions it can be
    applied to. What exactly does the Choi-Williams do with my signals. In
    how far is it different to FFT?
    Take your time to reply. All of them will be posted as usual, but it
    will take a while as I will not be in the office in August.
    Thanks in advance to all who will respond.

    Yours


    Axel
