emitter coupled logic (ECL)
A logic device family in which current is steered through bipolar tran-
sistors to compute logical functions. The chief characteristic of ECL is
that the transistors are always in the active region and can thus change
state very rapidly, allowing ECL circuits to operate at very high speed.
36, 47, 48
extensible display manager (EDM)
A tool that manages a collection of active displays with the ability to
create and edit display content as well as the ability to execute the
same content resulting in the dynamic presentation of live data. 15–17
experimental physics and industrial control system (EPICS)
A set of software tools and applications used to develop distributed soft
real-time control systems. 6, 10, 12, 15, 16, 21, 34, 57
Ethernet
A family of frame-based computer networking technologies for local
area networks. 5, 9
fast Fourier transform (FFT)
An efficient algorithm to compute the discrete Fourier transform. 27
finite impulse response (FIR)
A discrete-time filter, output of which only depends on a finite number
of previous input samples. 4, 6, 17, 19, 20, 36, 41, 42
field programmable gate array (FPGA)
A semiconductor device containing programmable logic components
and programmable interconnects. 5, 6, 12, 13, 15, 19, 24, 36, 41, 42,
44–49
full-scale (FS)
Difference between maximum and minimum limits of the signal. For
example, DAC full-scale is the difference of the outputs for maximum
and minimum codes. 6, 9, 36
