#83: Basics of RF Mixers in Radio Receivers / Mixer Tutorial / Frequency Conversion

This video describes the basic properties of RF mixers, in the context of using them for frequency conversion/translation such in the application of a radio receiver. The input and output signals are shown on the oscilloscope, and the spectrum of the output is also shown, illustrating the various frequency components that are produced by the mixing process. The concept of IF filtering in a receiver is also illustrated. The video does not go into the design of mixers, the different types of mixers, or how to select a mixer for a given application.
