I2R LOSSSee COPPER LOSSES [11]. | |
IC SYNCHROSObsolete synchros with reverse rotation and limited torque capabilities [15]. | |
IDEMPOTENT LAWIn 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 LAWIn Boolean algebra, the law which states that any expression is equal to itself | |
IDLER FREQUENCYIn a parametric amplifier, the difference between the input signal and the pump signal frequency. Also called the LOWER-SIDEBAND FREQUENCY [11]. | |
IF AMPLIFIERUsually a narrow-bandwidth IF amplifier that is tuned to one of the output frequencies produced by the mixer [18]. | |
IGFETAny field-effect transistor that has an insulated gate [7]. | |
IMAGE FREQUENCYAn undesired frequency capable of producing the desired frequency through heterodyning [17]. | |
IMPEDANCEThe 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]. | |
IMPLOSIONThe inward bursting of a CRT because of high vacuum. The opposite of explosion [6]. | |
