Question

Power Amplifiers

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: 1k?, 50k?
  • 3 capacitors: 0.1µF, 0.01µF, 560pF
  • 1 inductor: 38.07µH
  • Tektronix oscilloscope
  • Waveform generator

PROCEDURE

Using Multisim construct the circuit shown below:

Diagram posted as attachment

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

  1. Use the Waveform generator to produce an input: 2.5Vpk and frequency set to the resonant frequency.
  2. Use the Tektronix oscilloscope to measurefoutand record it in the table
  3. Take a screen shot of circuit showing the frequency measurement on the oscilloscope.
  4. Repeat steps a) and c) for each input frequency in the table.
