Short time energy matlab code
Splet12. maj 2014 · I'm writing a Matlab program to perform a convoluted sum of two signals. I first started out creating a simple sinusoidal signal and a carrier signal. I convoluted the two and created the convoluted signal. You can see that my (x) axis is specified in the time domain. My code and a screen shot of my plot is shown below for clarity. MY CODE: SpletI have a homework about ' Finding and plotting Short - Time Energy, Short - Time Zero crossing, ST autocorrelation and Pitch estimation in Matlab with 2 seconds of my voice ( for example : saying 'a' 2 seconds and 'z' 2 seconds) I have 2 days for finishing it and I have been trying to do that for 3 weeks but I can not.
