DEFINITION
Amplifier with a constant output level with
i n p u t s i g n a l l e v e l e i t h e r i n c r e a s i n g,
decreasing, or remaining constant.
Process of varying the amplitude, frequency,
or phase of a carrier or signal.
Increases contrasts.
I l l u m i n a t i o n t h a t w i l l n o t r e g i s t e r on
o r t h o c h r o m a t i c f i l m .
Hub which permits different diameter cores
to be used.
Substance that emits light when excited by
r a d i a t i o n.
E l e c t r o n m u l t i p l i e r i n w h i c h e l e c t r o n s
released by photoelectric emission are
multiplied in successive stages by dynodes
that produce secondary emission.
Photomultiplier Tube.
Device for measuring and controlling
e l e c t r o m o t i v e f o r c e s.
Allows individual selection of raster edge
position by varying resistance.
Automatically advances paper when hood is
r a i s e d.
Roll Paper Transport.
Multivibrator capable of assuming either of
two stable states.
Determines number of lines to expose entire
negative and spacing between lines.
Array of components of emission or wave
separated and arranged in order of some
varying characteristic, such as wave length
mass or energy.
