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). Set Winscope to the settings shown
on the upper right, and move the lever on the adjustable resistor
(snap part RV) around to change the waveform and the sound. At
some positions there may be no sound. A sample waveform is
shown on the upper right.
You can also change to the
0.5ms/div scale to take a closer
look at one of the pulses, shown on
the right:
