Lecture 20. 1. Review: The periodogram.

In signal processing, a periodogram is an estimate of the spectral density of a signal. The term was coined by Arthur Schuster in 1898. Today, the periodogram is  Estimates of the spectral density are computed using what is known as a periodogram — which in turn is computed via the famous fast Fourier transform.

Obtain the periodogram of an input signal consisting of a discrete-time sinusoid with an angular frequency of rad/sample with additive white noise. Create a sine wave with an angular frequency of rad/sample with additive white noise. The signal is 320 samples in length. Obtain the periodogram using the default rectangular window and DFT length.
