#### RESOLVER

A rotary, electromechanical device used to perform trigonometric computations by varying the magnetic couplings between its primary and secondary windings. It is generally used in circuits that solve vector problems, such as analog computers and conversion equipment. The resolver solves three different type problems: (1) Resolution - separating a vector into two mutually perpendicular
components; (2) Composition - combining two components of a vector to produce a vector sum; and (3) Combination - the process of resolution and composition taking place simultaneously [15].

#### RESONANCE

The condition in a circuit containing inductance and capacitance in which the inductive reactance is equal and opposite to the capacitive reactance. This condition occurs at only one frequency and the circuit in that condition is said to be in resonance [2] [9] [10].

#### RESONANCE CHAMBER

See ECHO BOX [18].

#### RESONANT CIRCUIT

A circuit that contains both inductance and capacitance and is resonant at one
frequency (XL = XC) [9].

#### RESONANT FREQUENCY

That frequency in a given resonant circuit at which the inductive and
capacitive reactance values are equal and cancel each other [9].

#### RESONANT LINE

A transmission line that has standing waves of current and voltage [10].

#### REST FREQUENCY

The carrier frequency during the constant-amplitude portions of a phase
modulation signal [12].

#### REST POSITION

See REFERENCE LINE [10].

#### REST TIME

(RT)â€”The time when there is no pulse; nonpulse time [12].

#### RESULTANT MAGNETIC FIELD

The magnetic field produced in a synchro by the combined effects of the three stator magnetic fields [15].
