A "bias tee" consists of a single output that is capacitively coupled to a radiofrequency signal and inductively coupled to a DC signal. What is the primary purpose of this device?

Dithering of an audiofrequency signal typically occurs at what stage?

The self-induced back voltage in a circuit that occurs when an inductive DC circuit is opened may be safely routed away from the switch with a diode connected across the inductor and against the DC voltage. What is the main disadvantage of this practice?

What is Wein Bridge used for?

In a system with a transmission multiplexer and a reception demultiplexer, how many outputs is it typical for the multiplxer to possess?

A high-voltage primary circuit is isolated with the use of a relay switch on a secondary circuit. Does the addition of the relay circuit add inductance to either circuit?

True or False? Lightbulb power ratings are only correct for the rated voltage.
