Amplitude Ratio Measurement with Matlab
The present code is a Matlab function that provides a measurement of the amplitude ratio between two signals with one and the same shape (e.g., both signals are sine-waves). The main purpose is assisting the measurement of a frequency response of a two-port circuit. The amplitude ratio measurement is based on a Discrete Fourier Transform (DFT) of the signals and a Maximum Likelihood Estimation (MLE) of their amplitudes. The method is highly noise resistive.
Two examples are given in order to clarify the usage of the function. The input and output arguments are given in the beginning of the code.
The code is based on the theory described in:
