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… Web• When the sum frequency is used as the IF, the mixer called anupconverter; when the difference is used, the mixer is called a downconverter. The former is often used in a transmit channel, the latter in a receive channel.
