Schottky Barrier Diode
Schottky Barrier Diode Schottky Barrier Diode is a simple metal-semiconductor interface exhibiting anon-linear impedance and is basically an extension of the point-contact diode. When the diodes are forward biases current…
Transmission Errors
Transmission Errors No physical medium can guarantee error-free transmission of data. Errors occur because of interference from the environment surrounding the transmission medium or because of artifacts introduced by the…
Colour Signal Transmission
Colour Signal Transmission Colour Signal Transmission: The colour video signal contains two independent pieces of information, that of hue and saturation. It is a difficult matter to modulate them to…
Solid-State Image Scanners
Solid-State Image Scanners Solid-State Image Scanners: The operation of solid-state image scanners is based on the functioning of charge-coupled devices (CCDs) which is a new concept in metal-oxide-semiconductor (MOS) circuitry.…
Plotter | Types – Drum Plotter, Flatbed Plotter
