Periodic Sounds PC
OBJECTIVE: To look at the output of an alternately changing
circuit.
Build the circuit shown. If continuing from the previous experiment
then close the Winscope program and run it again, to reset the
settings. Click on the On-Line button to activate, and turn on the
slide switch (snap part S1). Try the
settings shown here.
The oscilloscope display alternates between 2 waveforms, the one
shown here and the one on the next page. This one shows some
pulses followed by a flat signal, then more pulses, then flat, then
pulses, then flat . . .
This is the second oscilloscope waveform, using the same settings.
It is a continuous series of pulses. You can use the
Hold button to
freeze the display for easier viewing.
