noisin

Estimates the amplitude, frequency, and DC offset of a sampled noisy sinusoid.

MATLAB function to estimate the amplitude, frequency, and DC offset of a sampled noisy sinusoid. Choice of RMS or spectral methods available for amplitude estimation, with a decision guide.

Usage:

[Amplitude,Frequency,DC] = noisin(data vector,sampling rate,'method')

Note: Accuracy and generality, rather than efficiency, are emphasized in noisin.m.
