Signals and Comms 2, Lecture 7, Part 2/3: Orthogonality of Fourier and Walsh Basis Functions

This lecture applies the concept of orthogonality to discuss representing a signal as a linear combination of building block signals, or basis functions. The orthogonality of complex phasors in Fourier analysis is presented, along with a discussion of the applicability of Walsh functions. Reference to other basis functions is also made.

plz can u do another video explaining how to find coefficients, and representing signals using a given Walsh functions!
