GLOSSARY
OF
TERMS
MPPS
Bistable
(multivibrator)
Calibrate
A
circuit
that
has
two
stable states
and
requires
two
input
pulses
to
complete
a
cycle.
To
check
or
correct
the
graduation
ac
curacy
of
quantitative
indicators.
CAL
(calibrated)
position
An
index
position
to
which
an
otherwise
ungraduated
control
is
set
when
a
quanti
tative measurement
must
be
made.
Catching
or
clamping
diode
Establishes
the
+
or —
extremity
of
a
volt
age
excursion.
Count-down
(of
pulses) circuit
Delayed
pulse
Overshoot
PPS
Preshoot
Pulse
amplitude
Pulse
duration
A
circuit,
such
as
a
bistable,
whose
output
consists
of pulses fewer
in
number
(usu
ally
a
submultiple)
than the
pulses
applied
to
the
input(s).
A pulse
occurring
after
a
preselected
in
terval
following
an
event
used as
a
time
reference
point.
Delayed
trigger
Duty
factor
(of
pulses)
Enabling
pulse
External
trig
ger
(pulse)
Falltime
Generally,
a
narrow,
delayed
pulse.
For periodic
pulses,
the duty
factor
(often
called
duty
cycle)
is
equal
to
the
duration
(width)
of
a
pulse
divided
by
the
pulse
period.
A
pulse which
opens
a
normally closed
electric
gate,
or
otherwise
permits
an
oper
ation
for
which
a
pulse
input
is
a
neces
sary
condition.
An
enabling pulse
derived
from
a
source
external
to
the
circuit
or
equipment
where
a
particular
operation
requires
an
enabling
pulse
with certain
characteristics
(time
de
layed,
duration,
etc.).
The
time required
by pulse waveform
to
fall
from
90%
of its
maximum
value
to
10%
of its
maximum
value.
Not
neces
sarily
equal
to
risetime.
Jitter
KPPS
Pulse
period
Pulse
Repeti
tion
Frequency
Pulse width
Quiescent
Ramp
voltage
Ringing
Risetime
Short-duration
instability
(of
a
signal); ran
dom
small
departures
from regularity.
Kilopulses
per
second.
Monostable
(multivibrator)
A circuit
having
one
stable
and
one semi
stable
state.
A
trigger
pulse
drives
the
circuit
into
the
semistable
state,
where
it
remains
for
a predetermined time
before
returning
to
the
stable
condition.
Sampling
system
Trigger
Megapulses per
second.
When
changing from
one
voltage
level
to
another,
a
momentary
excursion
greater
than
the
change desired.
Pulses
per
second.
A
small
negative excursion immediately
preceding
a
positive-going
pulse,
or
vice
versa.
The
amplitude of
a
pulse
is
any
term
indi
cating
the
magnitude
of
the
pulse.
The
time interval
between
the
first
and
last
instants
at
which
the
pulse
voltage
(or
current)
reaches
some
specified
percentage
of
the
peak
voltage
(or
current)
of
the
pulse.
The
pulse
period
in
a
sequence
of
periodic
pulses
is
the
elapsed
time
between
any
given
point
on
one
of
the
pulse
waveforms
and
the
same
point
on
the following
pulse.
The
number
of
periodic
pulses
that
occur
in
a
given
unit
of time.
Also
expressed
as
pulse
repetition
rate.
See
pulse duration.
At rest
—
specifically,
the
condition
of
a
circuit
when
no
input
signal
is
being
ap
plied
and/or
no
change is
taking
place.
A
voltage
waveform
that
rises
at
a
steady
rate.
For
example, at
10
volts
per
second..
High-frequency
damped
oscillations
caused
by
shock
excitation
of
high-frequency res
onances,
or,
a
damped
oscillation
in
the
output
signal
of
a
system
as
a
result
of
a
sudden
change
in
the
input
signal.
The
risetime
of
a
pulse
is
taken
as
the
time
required
for
the
leading
edge
of
the
pulse
to
increase
from
10% of
its
maximum
value
to
90%
of its maximum
value.
A
method that
takes
amplitude
samples
from
a
repetitive
input
signal with each
sample
at
a
progressively
later
time,
then
reconstructs
these
samples
into
a
replica
of
the
original
waveform
at
a
much
lower
frequency.
A
signal
that
starts
action
in
another
circuit.
