Types of radio modulation

There is a huge variety of different types of modulation or modulation techniques that can be used to superimpose information, either digital or analogue onto an RF signal.

Radio signal modulation formats

Although there is a large variety of different modulation techniques that can be used, different signal formats can be used along with these modulation techniques to enable radio signals to be used in differnet ways. Some of these techniques are given below:

Frequency Synthesizers

Frequency synthesizers are widely used in radio receivers. Upon their performance depends many of the parameters of the whole receiver. Particularly important is the phase noise performance as this can limit the performance of a complete radio communications system.
