Service
Digital logic circuits perform many functio n s with i n t he
instr u me n t . Fu nctio n s an d operatio n of t he logic circuits
are re p resented by logic symbology and terminology .
M ost logic functions are d escribe d using t h e p ositive-logic
convention .
P
ositive logic is α system of notation w h ere b y
t
h
e more p ositive of two levels is t
h
e T RUE (o r 1) state ;
t
he more negative level is t h e F
A L S
E (or
0) state
.
In t
h
is
logic descri p tion t h e T RUE state is referre d to as ΗΙ , and
t he F A L SE state is referre d to as L O . T h e s p ecific voltages
w h ic h con stitute α ΗΙ or α LO state vary between s p ecific
devices . F or sp ecific d evice ch aracteristics, refer to t he
man u fact ur er's d ata boo

d evices in t h is section use waveforms or ot h er tec h ni qu es
such as voltage measu rement an d simp lifie d d iagrams to
