The input force is a sine with unit amplitude and a frequency of 0.1 Hz. Undesirable components, such as decaying DC, if present in the input signal, are first attenuated using a complex-gain filter. A frequency estimator for a single complex sinusoid in complex white Gaussian noise is proposed and is more computationally efficient that the optimal maximum-likelihood estimator yet attains as good performance at moderately high signal-to-noise ratios.
