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 ...

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 ...

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 ...

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 ...

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 ...
