In digital signal processing, a digital down-converter (DDC) converts a digitized, band-limited signal to a lower frequency signal at a lower sampling rate in order to simplify the subsequent radio stages. The process can preserve all the information in the frequency band of interest of the original signal. The input and output signals can be real or complex samples. Often the DDC converts from the raw radio frequency or intermediate frequency down to a complex baseband sign… WebJun 20, 2024 · Just as when deciding whether to use Surround Sound Processing in the first place, deciding HOW you want it to work, is also, purely a matter of taste.
