Digital Signal Processing
Digital Signal Processing (DSP) is a vast and rich subject. One sees the convergence of many beautiful ideas from Physics, Mathematics and Electronics. While it can be difficult in some areas, the basic concepts and calculations can be understood with a few good examples based on the knowledge of just Higher Secondary level Physics and Mathematics.
