According to my previous question, I have changed the generate command to:
y=generate1(100,1000,1);
and got the following picture:
Now I want to test a wavelet transform on the same signal, which of course exists in Matlab, but I have one thing which I should clarify: generally, as I know large scale values correspond to small frequencies and small scale values to large frequencies. So, how should I determine if the given frequencies are small or large? Also, which wavelet transform should i use?
For example:
m=cwt(y,1:100,'sym2');
and plot it
plot(m)
How should I read the second picture? What kind of information can I get?
