Radio frequency (RF) signals

What is a radio frequency (RF) signal? In electronics and telecommunications, an RF signal refers to any time varying voltage, current or electromagnetic wave that carries information. The simplest form of signal is a simple sinusoid, and can be represented by mathematical functions with the following parameters to define it:

• Amplitude(will tell how much power the signal carries)
• Frequency(how fast the signal repeats)
• Phase(position of the signal in time)
