ABSTRACT:
A method of obtaining in-phase and quadrature phase components for a narrowband signal is provided. The method includes digitally sampling a narrowband signal at a digital sampling rate to obtain a number of data points. The method subtracts a first portion of the data points corresponding to a first half of one period of the signal from a second portion of the data points corresponding to a second half of the one period of the signal to obtain a number of output data points which is less than the number of data points obtained from sampling the narrowband signal.
