Short-time Energy and Zero Crossing Rate

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

Description

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.

Good work, man! It helped me a lot!

Thanks and good luck!

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