At the output of beamforming and the receiver channel, with a band-pass filter at the intermediate frequency (IF), the received signals are available for further processing. They are at this stage continuous analogue signals. For digital processing we need sampled values of the orthogonal components I and Q as described in Chapter 2 with (2.1). In this chapter we will discuss the necessary sampling rate and methods to derive the orthogonal components I and Q.
