Many applications require a circuit to perform pulse modulation and voltage amplification to drive a load with a train of impulses. A typical application is driving a piezoelectric generator in a ...

This video explains how transistors work and how they are used to switch and amplify electrical signals in electronic ...

In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air ...

Announced yesterday, researchers from Surrey and Cambridge universities and the National Research Institute in Rome have used thin-film source-gated transistor (SGT) to create compact analogue circuit ...

Researchers outline the first practical demonstration of carbon nanotube transistor based printed circuits for display backplane applications revealing CNT's viable candidacy as a competing technology ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

FN, Fowler–Nordheim tunnelling; DT, direct tunnelling. Editor’s summary The ultimate in electronic device miniaturization would be the creation of circuit elements consisting of an individual molecule ...

Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...

Back in 1966, a suitable toy for a geeky kid was a radio kit. You could find simple crystal radio sets or some more advanced ...
