Phase Equilibria

The model simulates asymmetric modulation which can be observed at second scope by zooming the waveform on time axis. In this modulation technique the reference signal is sampled at positive as well as at negative peak of the carrier and held constant between two sampled points. Three phase...

This function allows one to calculate the Fourier transform of a chirped function evaluated at specific points using the stationary phase approximation.Imagine a pulse with a large time-bandwidth produce: this would require a large amount of data points in order to evaluate the Fourier transform....
