AF114 germanium transistors and related ones like the AF115 through AF117 were quite popular during the 1960s, but they quickly developed a reputation for failure. This is due to what should have made ...

A new record has been set for extremely precise control over qubits, the building blocks of quantum computers. This advance could lead to quantum computers that make fewer errors – if it can be ...

Tone control is a type of equalization used to make specific pitches or “frequencies” in an audio signal softer or louder. A tone control circuit is an electronic circuit that consists of a network of ...

MANILA, Philippines — "Kalimutan Ka" by Filipino rapper Skusta Clee was the most-viewed music video in the Philippines, according to local data by YouTube. The song's music video released last ...

MANILA, Philippines — Acting Philippine National Police (PNP) chief Lt. Gen. Jose Melencio Nartatez Jr. on Wednesday maintained that the law enforcement agency’s morale “remains high” amid its efforts ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

Control of heat flow is crucial for thermal logic devices and thermal management, with theoretical exploration preceding limited experimental progress in actively controlling heat flow. The device ...

What is a Programmable Unijunction Transistor (PUT)? Simple – it is a three-lead electronic semiconductor device, similar to a unijunction transistor (UJT), except that its behaviour can be controlled ...
