- New / EnguhYr23Alan V. Oppenheim's book. Make sure you understand all verions of continuous and discrete time Fourier transform. Nyquist theorem is very important. Know frequency equivalent of time domain operations. Be fluent in writing fourier and inverse fourier equations. Learn about A/D and D/A. Know how DFT and FFT's work and how there're related to basic fourier transforms. Know a bit about wavelets, DCTs, and filter banks. These are very fundemental stuff.
