Fractional bandwidth definition
Fractional bandwidth. (3 5) means the "instantaneous bandwidth" divided by the centre frequency, expressed as a percentage.
Fractional bandwidth. (Categories 3, 5) means the “instantaneous bandwidth” divided by the centre frequency, expressed as a percentage; “frequency hopping” (Categories 5, 6) means a form of “spread spectrum” in which the transmission frequency of a single communication channel is made to change by a random or pseudo-random sequence of discrete steps; “frequency switching time” (Category 3) means the time (i.e. delay) taken by a signal when switched from an initial specified output frequency, to arrive at or within either of the following: a. ±100 Hz of a final specified output frequency of less than 1 GHz; or b. ±0.1 part per million of a final specified output frequency equal to or greater than 1 GHz; “fuel cell” (Category 8) means an electrochemical device that converts chemical energy directly into Direct Current (DC) electricity by consuming fuel from an external source; “Full Authority Digital Engine Control System” or “FADEC System” (Category 9) means a digital electronic control system for a gas turbine engine that is able to autonomously control the engine throughout its whole operating range from demanded engine start until demanded engine shut-down, in both normal and fault conditions; “fusible” (Category 1) means capable of being cross-linked or polymerised further (cured) by the use of heat, radiation, catalysts, etc., or that can be melted without pyrolysis (charring); “Gate-All-Around Field-Effect Transistor” or “GAAFET” (Category 3) means a device having a single or multiple semiconductor conduction channel element(s) with a common gate structure that surrounds and controls current in all of the semiconductor conduction channel elements; N.B.“Gate-All-Around Field-Effect Transistor” includes nanosheet or nanowire field-effect and surrounding gate transistors and other “GAAFET” semiconductor channel element structures. “hard selectors” (Category 5) means data or set of data, related to an individual (e.g. family name, given name, e-mail, street address, phone number or group affiliations); “guidance set” (Category 7) means systems that integrate the process of measuring and computing a vehicle’s position and velocity (i.e. navigation) with that of computing and sending commands to thevehicle’s flight control systems to correct the trajectory;

Containing at least one unencapsulated device; b. Connected together using typical IC production methods; c. Replaceable as an entity; and d. Not normally capable of being disassembled;
