Connect
the
Voltage Amplifier output
to the
F.M.
Input socket.
No DC
Offset
is
required.
The gain
of the
Voltage Amplifier
is
used
to
vary the
waveform^ and
Inversion of the
waveforms can be accomplished by
reversal of
the
Voltage Amplifier input connections.
The waveforms
are as
above.

MISCELLANEOUS
WAVEFORMS PRODUCED
BY AMPLITUDE
MODULATION:
Connect
the
6.3V
AC
terminal via
a 39Ki^
resistor to
the
A.M.
input
socket.
Also connect
the
OV A.C.
terminal
to
any ground
( )
terminal.
The frequency
of
the
modulating
signal
is
then equal
to
the
mains frequency,
i.e.
50
or
60Hz.
With
the
A.M.
switched
ON
and
the
Function Generator frequency
set to
IHz,
the following waveforms can be displayed:-
Reset the
Function Generator frequency
to
IkHz.
