Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

Amplification is a process of increasing the signal strength by increasing the amplitude of a given signal with out changing its characteristics. Here we will concentrate how transistor is used as ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

THE properties of the amplifier to be described are entirely due to the type of transistor used, and the purpose of this communication is to report on its suitability for the amplification of ...

Someone brought a dead Marantz amplifier to [Lansing]’s attention, a rather nice model from the 1980s with one channel entirely dead and the other very quiet. His account of its repair is ...
