Matlab: Analysis of signal
- by Mateusz
Hi, I have a problem with this task:
For free route perform frequency analysis and give parametrs of each signal component:
time of beginning and ending of each component
beginning and ending frequency
amplitude (in time domain) in the beginning and end of each signal's component
level of noise in dB
Assume, that, the parametrs of each component like amplitude, frequency is changing lineary in time. Frequency of sampling is 1000Hz
For example I have signal like this:
Nx=64;
fs=1000;
t=1/fs*(0:Nx-1);
%==========================
A1=1;
A2=4;
f1=500;
f2=1000;
x1=A1*cos(2*pi*f1*t);
x2=A2*sin(2*pi*f2*t);
%==========================
x=x1+x2;
