Moodle Activity Examples

A shipboard radar system used to guide aircraft to safe landings in poor visibility conditions [18].

(1) One or more digits, produced in connection with an arithmetic operation, that is/are forwarded to another digit place for processing there. (2) The number represented by the digit or digits in (1) above [13].

In a velocity-modulated tube, a grid on which the spaced electron groups induce a signal. The output of the tube is taken from the catcher grid [11].

(1) In an electron tube the electrode that is the source of current flow [6]. (2) The general name for any negative electrode [1]. (3) The negative terminal of a forward-biased semiconductor diode, which is the source of the electrons [7].

The method of biasing a vacuum tube in which the biasing resistor is placed in the common-cathode return circuit, thereby making the cathode more positive with respect to ground [6].

A system in which the cathode circuit is interrupted so that neither grid current nor plate current can flow [12].

Voltage on the cathode is varied to produce the modulation envelope [12].

A process of producing thin film components [14].

An electron tube that has an electron gun, a deflection system, and a
screen. This tube is used to display visual electronic signals [6].

A space totally enclosed by a metallic conductor and supplied with energy in
such a way that it becomes a source of electromagnetic oscillations. The size and shape of the enclosure determine the resonant frequency [11].
