Sound can be represented with both analog or digital audio signals. Analog audio signals use electrical voltage levels. Different types of transducers convert sound to electrical signals and ...

Audio amplifier fault diagnosis gets a fast reality check as Roberto Armani shows how a square wave exposes what a sine wave ...

In 2015, there’s not much question about audio storage, transmission, or streaming: it’s digital. Apart from rare sightings of vinyl or open-reel tape in boutique sales or creative enclaves, audio is ...

As the Internet of Things in all its manifestations continues to roll out, developers will need a variety of test strategies to ensure low power consumption, suitable RF performance, and even audio ...

A small audio test generator is very useful for quickly tracing a signal through an audio unit. Its main purpose is speed rather than refinement. A single sine-wave signal of about 1 kHz is normally ...

In parts one and two, I made a case for the idea that real power handling was intimately tied to the nature of the signal, as well as the electromechanical parameters of the speaker under test. We ...
