Moodle Activity Examples

See LOBE [18].

Semiconductor chip with electrodes (leads) extended beyond the wafer [14].

An electron tube in which the grids are aligned with the control grid. Special
beam-forming plates are used to concentrate the electron stream into a beam. Because of this action, the beam-power tube has high power-handling capabilities [6].

An angular measurement of the direction of an object from a reference direction, such as true north [11].

Ability of a radar to distinguish between targets that are close together in
bearing [18].

Difference and sum frequencies, which result from the combination of two
separate frequencies [18].

The difference between the oscillator frequency and the unknown audio frequency
[16].

An additional oscillator used in a receiver when it is receiving a
cw signal. It provides an audible tone [17].

The unit that expresses the logarithmic ratio between the input and output of any given component, circuit, or system [16].

The ratio of a change in collector current to a corresponding change in base current when the collector voltage is constant in a common-emitter circuit [7].
