I'm new to Matlab.As a beginner, I want to work on few signals which are used in day today life and extract useful information through it. Can someone please help me from where I could start or share a blog which might help me with this. Thank you.
Your question is a bit broad. Since you probably have Matlab (I hope), Matlab help is where to start, for instance Measurements and Feature Extraction. From there, you can start with signals available in Matlab, get some tutorial code, etc.
