This allows the extraction of the in-phase and the quadrature component that can then be transferred into polar coordinates, i . e . amplitude and phase, or further processed as real and imaginary part of a complex number ( e . g . for complex FFT analysis ).
12.
Given the previous example to be processed with this method, assume real-valued data ( as opposed to complex data, which would have in-phase and quadrature components ), a sampling rate of 5 MHz, a signal window of 10 ms, and an intermediate frequency of 2.5 MHz.
