| Aim - To investigate how
the Op-Amp can be used to generate a square wave. |
Instructions |
| |
- Connect the oscilloscope across the inputs A B
|
- Adjust the signal generator voltage and the oscilloscope time base to obtain a suitable
trace.
|
| The settings are reduced by clicking on the left of the
dial and increased by clicking on the right of the dial. |
- Accurately sketch the pattern produced
|
- Now connect the oscilloscope across the output C D
|
- Without adjusting any of the controls sketch the pattern produced.
|
- State how the phase of the output V0 compares with the input
V1
|
- Compare the frequency of the output V0 to
the input V1.
|
- State the gain of the amplifier in this circuit
|
- Hence state the minimum value of V1 that will produce
a saturated output potential V0.
|
- As the input potential from the signal generator V1
is increased, explain what happens to the output potential V0
.
