How to Create a Carrier Sweep

Published on April 1, 2017 by Spooky2 Videos – This video shows how to create a carrier sweep. A carrier is a fixed frequency. More frequencies can be created if this frequency is turned on and off very rapidly. Another word for this is “modulation”. Usually this modulating frequency is quite high, so the switching cannot be observed. When a carrier frequency is modulated, multiple frequencies are created on either side of it. These are called “sidebands”. The modulation sets the distance between each of the sidebands. Imagine an inverted hair comb. Its teeth represent frequencies created by a modulated carrier. Each tooth is evenly spaced, in exactly the same way as modulating a carrier frequency makes evenly spaced frequencies, and the distance between each is the modulation frequency.
