These are my handwritten Digital Signal Processing notes. Third year, second semester, Electronics and Communication Engineering at BITS Pilani, Dubai Campus.
I joined in 2011. The method behind this notes library has always been the same: teach what you are learning, and teach it until it is clear. Teaching friends and classmates is how I learned. Understanding something deeply enough to teach it is the highest form of mastery.
The notes cover the discrete Fourier transform, the FFT, FIR and IIR filter design, and digital filter implementation. If you are doing lab work alongside the theory, the DSP MATLAB lab notes are on a separate page on this site.
In 2013, from a hostel room, I put my handwritten notes online so anyone who needed them could use them. Since then, at least one person in the world has studied from my notes every day. They are free.
The full notes are a PDF embedded on this page. Read them right here, or open and download them.
