What Does Digital Down Converter (DCC) Mean?
A digital down converter (DDC) is a component of a digital signal processing system where it is used to convert a digitized real signal centered at an intermediate frequency to a basebanded complex signal centered at a zero frequency. It is also used to reduce the input signal to a lower sampling rate, thus allowing lower-speed processors to process incoming fast signals.
Techopedia Explains Digital Down Converter (DCC)
Digital down converters typically perform the down conversion of incoming signals in a digital signal processing system. They are widely used in communication systems and radio receivers where the fast analog-to-digital converters (ADCs) deliver huge amounts of data that need to be down converted. A DDC takes the output signals from the ADC and allows for intensive processing of the specific data by discarding the rest of the data.
