That's the test-equipment hardware challenge. Equally or more important is knowing how to make the measurements. The plusses and minuses of simply measuring audio amplitude take up a page and a half ...

Testing FM receivers is not that much different than testing other pieces of audio equipment. Appropriate tests include the big six: level, frequency response, THD+N, phase, interchannel crosstalk, ...

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

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 ...

The audio analyzer can measure electrical performance only at the output jacks available on the system under test. Therefore, no one can enforce the speaker performance because the speaker is enclosed ...
