In effect, it is rated for AC operation and ... as a linear (adjustable) attenuator. I grew up in Massachusetts. I cut my teeth on electrical cord and learned how not to splice such by age 7. Started ...

For frequencies greater than 20 Hz, C1’s impedance can be considered as an AC short circuit. Let’s look at Figure 3 below: Figure 3 N Channel JFET attenuator circuit. In Figure 3, maximum attenuation ...

But first, we need you to sign in to PBS using one of the services below. We've talked about AC Circuits, but now it's time to delve into the world of AC Circuits (or Alternating Currents).

This Idea For Design shows how a gyrator circuit can be used to perform certain ac tests on units under test that require a dc-current feed. Designers have long used the gyrator circuit to create ...
