CIRCUIT
DESCRIPTION
4.
l
The
1kHz
signal
connected
to
the
input
is
ac
coupled
by
transformer
T
-1
.
The
secondary
is
connected
to
a
low-pass
filter
and
the
input
signal
subsequently
applied
to
the
AMP-LIMITER
(Ul,
Ql
and
QZ).
4.

The
waveform
at
the
output
of
the
AMP-LIMITER
is
a
rectangular
pulse
and
is
applied
to
a
divide
by
two,
(t
UZ) .
The
complimentary
outputs
of
the
divide
by
two
are
connected
to
two
separate
phase
shift
detectors.

(U3)
.
4 . 4
One
half
of
U3
provides
a
signal
in
quadrature
with
the
input
signal
to
the
phase
d~tector
enclosed
in
the
lock
loop.
The
out-
put
signal
is
averaged,
filtered,
amplified
=::::::::::
and
the
resulting
sign:al
used
to
control
the
local
voltage
controlled
o_
scillator.
The
response
of
the
lock
loop
is
essentially
speeded
up
when
switch
S-7
is
in
the
ADJ.
FOR
MINIMUM
position.
This
fast
response
facilitates
locking
the
local
oscillator
to
the
input
signal
frequency
.

With
switch
S-7
in
the
READ
position,
the
lock
loop
response
is
slow
enough
to
allow
measurement
of
phase
jitter
with
low
modulation
frequencies.
Typically
as
low
as
10Hz.

The
other
half
of
U3
is
connected
to
the
other
phase
detector
.
The
width
of
the
rectangular
pulse
appearing
at
the
outpu
·t
of
this
phase
detector
varies
with
the
phase
shift
of
the
incoming
signal.
This
pulse
is
applied
to
a
circuit
which
converts
the
pulse

variations
to

variations
(QlO
and
