Instructions
-
Connect the wires as shown in the figure.
-
Set PV1 to 2 volts.
-
Graph of DC will be a horizontal line.
-
Now set W1 to 1000Hz. This means the voltage output from W1 will oscillate between 3V and -3V 1000 times every second.
-
From the graph, note the times when the voltage crosses 0 Volts in the upward direction.
-
Measure the time for one cycle and calculate the frequency from that. Verify that it is close to the set frequency.
-
You may also use the ‘fit’ function by using the checkbox next to A2 in the controls section, and this will automatically derive a precise value of the frequency for you.
