9.4 Basic Junction Transistor Circuit Configurations As in the case of the thermionic valve, there are a number of layouts, in addition to the simple single transistor amplifier shown in Figure 9.4 or ...

[Part 1 covers the basics of bipolar junction transistors and looks at some typical BJT audio circuit configurations.] 9.7 Junction Field Effect Transistors (JFETs) JFETs are, almost invariably, ...

Explore the fascinating world of audio amplifiers with our hands-on experiments that you can easily try at home! This video guides you through the science of amplifying sound, explains essential ...

During normal operation, the incoming audio signal sees little attenuation by the diode network, and the high input impedance of U1 prevents attenuation due to the higher source impedance.

This article discusses the Audioholics testing methodology for measuring amplifier performance in receivers and power amps. We discuss the relevancy of the measurements and how they can affect sound.
