A DC bias can be used to power microphones or other devices over the same wires as required for the signal.

Frequency-shift keying can be done solely by changing the DC bias.

The roller will also apply a DC bias on the drum surface to ensure a uniform negative potential.

This method is particularly suited for instrumentation where signals are transmitted through DC bias.

"One" is represented by one physical level (such as a DC bias on the transmission line).

In either formulation, varies with DC reverse bias , as is observed in practice.

DC bias is the addition of a direct current to the audio signal that is being recorded.

DC bias was re-adopted by some very low cost cassette recorders.

Although the improvements are marked with such DC bias, even more dramatic improvement results if an alternating current bias is used instead.

The ratio of even and odd harmonics can be controlled by applying a DC bias to the photoresistor.
