Voltage Gain Estimation

21. Unplug the jumpers from J28 and J29.

= 470  by connecting jumpers to J30 and J31.

22. Set R

23. Set the function generator output to 40 mVpp and the output frequency to the resonance

frequency value measured earlier.

24. Connect the function generator output to TP1 and reference to GND.

25. Connect the oscilloscope CH1 to TP1 and GND.

26. Connect the oscilloscope CH2 to TP6 and GND.

27. Set the trigger signal to CH1.

28. Record the peak-to-peak voltage at the input (CH 1) and output (CH 2), and determine the

magnitude of the voltage gain, A

29. Determine the amplifier voltage gain using

calculated earlier. Compare the calculated value with the value measured in step 28.

30. Repeat steps 28 and 29 for R

connecting the jumpers to J28 and J32.

31. Turn off the power supply and disconnect all the cables from the Class A Tuned Amplifier

section.
