The principle of diode detection is rectifying the signal (AC component) through a diode and generating voltage as DC component. The detection makes use of the non-linear characteristic of the Schottky diode, so a bias circuit is not necessary.

Explanation:
The diode detector is the simplest and most basic form of amplitude modulation, AM signal detector and it detects the envelope of the AM signal.
The AM diode detector can be built from just a diode and a few other components and as a result it is a very low cost circuit block within an overall receiver. In the early days of radio, these signal detectors were made using discrete components, but modern radios will use integrated circuits with inbuilt detectors.
