The biasing current will enter directly this base and indirectly (through the input source) the other one.

The primary input sources are microphones for live announcements and a source of recorded sound.

This is also where you adjust the input source, the monitoring images, and recording level.

Because air is the input source, pneumatic actuators are able to be used in many places of mechanical activity.

The output resistance is low and is determined by the input source.

The design of channel codes should consider the correlation between input sources.

Then the input binary sources are compressed into of total bits.

A unique property of circuits with parallel positive feedback is the impact on the input source.

The energy to increase the current I comes from the input source.

Alternatively, the input source and the ground may be swapped.
