RHO

Greek letter "rho" (ρ). Used in the field of electricity and electronics to represent the specific resistance of a substance [4].

RHOMBIC ANTENNA

A diamond-shaped antenna used widely for long-distance, high-frequency
transmission and reception [10].

RIGID COAXIAL LINE

A coaxial line consisting of a central insulated wire (inner conductor) mounted
inside of a tubular outer conductor [10].

RIGIDITY

The tendency of the spin axis of a gyro wheel to remain in a fixed direction in space if no force is applied to it [15].

RING TIME

In radar, the time during which the output of an echo box remains above a specified level [18].

RINGING

RF oscillations caused by shock excitation of a resonant circuit or cavity [18].

RIPPLE FREQUENCY

The frequency of the ripple current. In a full-wave rectifier it is twice the input-line frequency [6].

RIPPLE VOLTAGE

The alternating component of unidirectional voltage. (This component is small
compared to the direct component.) [6]

RL DIFFERENTIATOR

An RL circuit in which the output is taken from the inductor [9].

RL INTEGRATOR

An RL circuit in which the output is taken from the resistor [9].
