This post describes the relationship between signal bandwidth and data rate. It also discusses Nyquist and Shannon’s criteria for deriving the channel capacity for different types of communication channels.
Bandwidth Estimation of a Signal using Fourier Analysis
This post explains the use of Fourier series in finding out the bandwidth occupied by any electomagentic signal. The post describes the Fourier series representation for a periodic signal as well as for an A-periodic signal.
