amplitude modulation

Amplitude modulation AM demodulation

The process of separating or extracting the modulation from a signal is called demodulation or detection. For amplitude modulation, the process of demodulation or detection can be accomplished very simply using a diode, or it may be achieved in other ways that provide more effective demodulation of the waveform. As amplitude modulation is still widely…

What is Amplitude Modulation

In order that a steady radio signal or “radio carrier” can carry information it must be changed or modulated in one way so that the information can be conveyed from one place to another. There are a number of ways in which a carrier can be modulated to carry a signal – often an audio…

FM Demodulation / Detection Tutorial

Frequency modulation is widely used for radio transmissions for a wide variety of applications from broadcasting to general point to point communications. Frequency modulation, FM offers many advantages, particularly in mobile radio applications where its resistance to fading and interference is a great advantage. It is also widely used for broadcasting on VHF frequencies where…
