About this document
Unit 1 by Suresh Kumar is a document available to read on EtoBox.
This document discusses discrete Fourier transforms and sampling theory. It introduces discrete time signals and their properties. It then derives the sampling theorem and expression for reconstructing a signal from its samples. Key points are that a signal must be sampled at least twice its maximum frequency to avoid aliasing, and that bandlimited continuous signals can be reconstructed from samples taken at the Nyquist rate.
