INTRODUCTION

Discuss some of the basic differences between the operation of a class A, B and C amplifiers.

EQUIPMENT

- 1 power supply: 12V
- 1 transistor: 2N3904
- 2 resistors: 1kΩ, 50kΩ
- 3 capacitors: 0.1µF, 0.01µF, 560pF
- 1 inductor: 38.07µH
- Tektronix oscilloscope
- Waveform generator

PROCEDURE

Using Multisim construct the circuit shown below:

Calculate the resonant frequency fr - show your work and record the answer in row 1 of the table.

a. Use the Waveform generator to produce an input: 2.5Vpk and frequency set to the resonant frequency.

b. Use the Tektronix oscilloscope to measure fout and record it in the table

c. Take a screen shot of circuit showing the frequency measurement on the oscilloscope.

d. Repeat steps a) and c) for each input frequency in the table.
