Abstract
An apparatus for determining a frequency component of a signal exploits the aliasing effect by sampling the signal at the frequency of the component (or an integer multiple thereof) to produce first and second sets of samples at the sampling frequency. Corresponding samples of the first and second sets of samples are separated in phase by substantially 90.degree.. The apparatus vectorially determines the magnitude and phase of the frequency component of the signal from the first and second sets of samples.
