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 ...

The behavior of analog circuits can often be characterized by sweeping their inputs with a signal going across a range of frequencies and then observing the output. These sweeps can be composed of ...

Oscilloscopes and to lesser extent signals generators are useful tools for analyzing, testing and diagnosing circuits but we often take for granted how they work. Luckily, [FromConceptToCircuit] is ...

Many types of signal generators and oscillators are used for EMC testing. Of them, lightning simulators are, without doubt, the most exciting. The maximum peak current that designers need to consider ...

The “envelope” of an oscillating signal is a smooth curve outlining its extremes. We can use such an envelope to help us control our audio-reactive artifacts. As you may recall from my previous MEGEQ7 ...

The author is senior development engineer for Wheatstone Corp. There’s nothing like a little audio performance testing to cap off a hectic week at the station, especially if you don’t have to haul out ...
