Envelope Detction for Signal Analysis软件

Computes the envelope of the signal by two methods: 1.LPF method 2.Hilbert Transform

软件应用简介

y=envelope(Signal,Fs) computes the Envelope of the input Signal with a Sampling Frequency ‘Fs’ and gives the envelope signal by Hilbert transform method as the output y. 

The function computes the envelope of the signal by two different methods.

First Method: By Using Low Pass Filter. The Signal is Squared, passed 

through LPF and then taken square root. 

Second Method: Using Hilbert Transform. Hilbert Transform is taken using the inbuilt function in Matlab

The Function Displays the FFT of the original signal and also the FFT of 

the envelope signal by both the methods

The function basically is for computing Envelope Signal for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis.

Example: 

load(‘s4.mat’); 

signal=s4; 

Fs=12000; 

envelope(signal,Fs);
