DEFINITIONS
For purposes
of this
specification, the
following
are
definitions
of
some
of
the
terms:
AMPLITUDE ASYMMETRY:
Is
the ratio of half of the
algebraic
sum
of
the plus
and
minus
*peak
values
of
a
waveform
to
the
*peak
to
peak value
of
the
waveform.

JITTER:

SETTLED
VALUE:
TIME
ASYMMETRY:
Is
the ratio of the
time difference
between any two
adjacent
half
cycles
of the
same
polarity
to
the indicated
cycle
length.
Of
a
waveform
is
the
arithmetical
sum
of the plus
and
minus
*peak
value
s
Of
a
square
wave
is
the
mean
value
taken over
the final half of
the half
cycle
disregarding
the final
100 nsec,
before an axis crossing.
Is
one-half
of
the
time difference be-
tween any two
adjacent half
cycles
divided
by
the
indicated cycle length.
TRANSIENT ABERRATIONS:
Are momentary
voltage deviations
from
the
apparent
ideal
behavior
of
a sine or triangle
waveform. *Peak
values and
triangle linearity
are
measured
exclusive
of
^transient
aberrations within
the stated limits.
