The circuit was designed to create a volume unit meter that would be used to measure the intensity of audio or sound level. Volume Unit (VU) – an entity equal to a decibel for expressing the magnitude ...

Given its appearance in one form or another in all but the cheapest audio gear produced in the last 70 years or so, you’d be forgiven for thinking that the ubiquitous VU meter is just one of those ...

The circuit was designed based on the functionality of LM3915 integrated circuit to produce a volume unit meter (VU Meter) that will be connected to the output of power amplifier. Power Amplifier – a ...

VU stands for volume unit (the other common type of audio meter is the PPM or Peak Programme Meter). A VU meter is essentially a voltmeter calibrated to give a reading of 0VU when fed with a sine wave ...
