Learn how microphones and amplifiers work together to convert sound to electrical signals for clear audio output.

a very simple op amp circuit with some detail omitted If you open this circuit in the Falstad simulator, you’ll see two sliders to the right where you can tweak the input voltage. If you make ...

If you ever wanted to build your own tube amplifier but you were intimidated by working with high voltages, [Marcel]’s low-voltage tube amp design might spark your interest. The design operates ...

Thermal noise current in MOSFET is given by Since noise voltages and currents are small, they can be represented as part of small signal model as shown below Noise Analysis of Common Source Amplifier ...

The pedal runs on 9V DC from a pedalboard power supply but internally boosts the voltage to 27V. There are three amp-style circuits and zero prizes for guessing the classic guitar amps that ...
