 Keyword(s): INERTIA

#### INFINITE

(1) Extending indefinitely, endless. (2) Boundless, having no limits. (3) An incalculable number [1].

 Keyword(s): INFINITE

#### INFRALOW FREQUENCY

The band of frequencies from 300 Hz to 3,000 Hz [19].
 Keyword(s): INFRALOW FREQUENCY

#### INFRASONIC

Sounds below 15 Hz [10].
 Keyword(s): INFRASONIC SUBSONIC

#### INPUT

The current, voltage, power, or driving force applied to a circuit or device [13].
 Keyword(s): INPUT

#### INPUT END

The end of a two-wire transmission line that is connected to a source [10].
 Keyword(s): INPUT END

#### INPUT IMPEDANCE

Impedance presented to the transmitter by the transmission line and its load [10].
