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 signal. (Wikipedia).
In this video I demonstrate the operation of a DC to DC converter and explain how it differs to a normal voltage regulator. Other equipment used during the demo: bench power supply, Fluke 115, Brymen TBM251 digital multimeter.
