### W

#### WAVE WINDING

An armature winding in which the two ends of each coil are connected to commutator segments separated by the distance between poles [5].

 Keyword(s): WAVE WINDING

#### WAVEFORM

The shape of the wave obtained when instantaneous values of an ac quantity are plotted against time in rectangular coordinates [2].

 Keyword(s): WAVEFORM

#### WAVEFORM ANALYSIS

Observation displays of voltage and current variations with respect to time or
by harmonic analysis of complex signals [16].

 Keyword(s): WAVEFORM ANALYSIS

#### WAVEFRONT

A small section of an expanding sphere of electromagnetic radiation that is perpendicular to the direction of travel of the energy [10].

 Keyword(s): WAVEFRONT

#### WAVEGUIDE

A rectangular, circular, or elliptical metal pipe designed to transport electromagnetic waves through its interior [10] [11].

 Keyword(s): WAVEGUIDE

#### WAVEGUIDE DUPLEXER

TR and atr tubes housed in a resonant cavity attached to a waveguide system.

 Keyword(s): WAVEGUIDE DUPLEXER

#### WAVEGUIDE MODE OF OPERATION

Any particular field configuration in a waveguide that satisfies the boundary conditions. Usually divided into two broad types: the transverse electric (TE) and the transverse magnetic (TM) modes [11].

 Keyword(s): WAVEGUIDE MODE OF OPERATION

#### WAVEGUIDE POST

A rod of conductive material used as impedance changing devices in waveguides [11].

 Keyword(s): WAVEGUIDE POST

#### WAVEGUIDE SCREW

A screw that projects into a waveguide for the purpose of changing the
impedance [11].

 Keyword(s): WAVEGUIDE SCREW

#### WAVELENGTH

The distance, usually expressed in meters, traveled by a wave during the time interval of one complete cycle. It is equal to the velocity divided by the frequency [2] [10] [12].
