crystal detector

The detector can be a crystal detector or a Schottky barrier diode.

It was further developed by Guglielmo Marconi, then replaced about 1907 by crystal detectors.

He experimented with crystal detectors, antennas, wave propagation, and noise suppression.

The crystal detectors, set for the characteristic emission wavelengths of plasma propulsion units, registered one flash of light after the other.

Deringhouse saw the uninterrupted flickering on the projection surface of the crystal detectors.

The crystal detector was the most successful of many detector devices that were used in the early days of radio.

It gets its name from its most important component, known as a crystal detector, originally made with a piece of crystalline mineral such as galena.

Perhaps, though, they would develop Alexanderson alternators for sending, which are nothing but specially designed dynamos; and receive by crystal detectors.

Receivers could be made with a tuned circuit, a crystal detector, and a headphone.

The coherer was replaced in receivers by the simpler and more sensitive crystal detector around 1907, and became obsolete.
