There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all rad… ...

Phase modulation Another form of modulation that is widely used, especially for data transmissions, is Phase Modulation (PM). As phase and frequency are inextricably linked (frequency being the rate ...

There are many different varieties of modulation but they all fall into three basic categories, namely amplitude modulation, frequency modulation and phase modulation, although frequency and phase ...

In practice, anomalies in the modulation process can cause the carrier frequency to vary slightly with the video signal level. The resulting time-varying frequency, and thus varying phase of the ...

This tutorial explains the fundamentals of time-, frequency-, and modulation-domain analysis from the perspective of several examples.

The graph below each modulated signal shows the instantaneous frequency during the course of the modulation. Negative frequencies as shown may be considered as equivalent to positive frequencies with ...
