Short-time Energy and Zero Crossing Rate

by

 

06 Apr 2009 (Updated )

Compute the short time energy (STE) and short-time zero crossing rate (STZCR) of a signal.

File Information
Description

Python version: https://github.com/nssh/dsp

This folder contains two simple functions (zerocross and energy) to compute STE and STZCR.

The script zcr_ste_so.m uses these two and other functions (included) to compute the STE and STZCR
of the word 'so'.

See the respective function help for more details.

how the hell are we suppose to fixe your "winlen" for energy function, it's the length of the window, i'm ruining myself by finding out how to determin it without lucky shot.

Thanx, already download and manage to run it

oh..remove already done..but i wonder which one is STE, ZCR and ZCRSTE??

Very nice funcion
Thank you!
I think that the output of the energy vector should be cut to the length of the original signal, at least that make sense in my work.

thanks all.

@John, its not a simple multiply. Please get some reference on zero-cross rate.

A good work!! But, why you use convolution to multiplicate the window in the ZCR? It's not a simple multiply?
