I2R LOSS

See COPPER LOSSES [11].

IC SYNCHROS

Obsolete synchros with reverse rotation and limited torque capabilities [15].

IDEMPOTENT LAW

In Boolean algebra, combining a quantity with itself either by logical addition or logical multiplication will result in a logical sum or product that is the equivalent of the quantity (for
example, A + A = A; A • A = A) [13].

IDENTITY LAW

In Boolean algebra, the law which states that any expression is equal to itself

IDLER FREQUENCY

In a parametric amplifier, the difference between the input signal and the pump signal frequency. Also called the LOWER-SIDEBAND FREQUENCY [11].

IF AMPLIFIER

Usually a narrow-bandwidth IF amplifier that is tuned to one of the output frequencies produced by the mixer [18].

IGFET

Any field-effect transistor that has an insulated gate [7].

IMAGE FREQUENCY

An undesired frequency capable of producing the desired frequency through
heterodyning [17].

IMPEDANCE

The total opposition offered to the flow of an alternating current. It may consist of any combination of resistance, inductive reactance, and capacitive reactance. The symbol for impedance is Z [2] [9].

IMPLOSION

The inward bursting of a CRT because of high vacuum. The opposite of explosion [6].
