Electronic engineering
crystal-lattice filter
Engineering; Electronic engineering
A crystal resonator in which piezoelectric crystals are used to give a desired shape to the filter response curve.
drag cup
Engineering; Electronic engineering
A cup of nonmagnetic metal (usually copper or aluminum) that, when rotated in a magnetic field, acquires a voltage proportional to the speed of rotation. The device is often used as a brake.
bidirectional current
Engineering; Electronic engineering
A current that flows in both directions. Utility alternating current (ac) is a common example.
cross current
Engineering; Electronic engineering
A current that flows in the opposite direction from some other current.
constant current
Engineering; Electronic engineering
A current that undergoes no change in value as it flows through a changing resistance. Compare constant voltage.
dynamic operating line
Engineering; Electronic engineering
A curve displaying the control function of a device. For example, the collector-current-versus-base-current curve of a bipolar transistor is drawn between the limits of saturation and cutoff.
composite curve
Engineering; Electronic engineering
A curve or pair of curves showing two modes of operation, as of biased and unbiased conditions.
