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 ...

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 ...

What's required in a source for mixed-signal test. Key factors in achieving low distortion. Designing a signal-generation path. What is digital predistortion (DPD)? Using LDOs to power the test system ...
