CHAPTER ONE 1.1 INTRODUCTION The increased development of electronic equipment and systems as led to more sophisticated machines and gadgets that for item to function properly require servicing and maintenance for better performance. This is achieved if the service technician has proper test equipment to analyze and test the faulty systems. The above problem can be solved by the use of function generator that provides test waveforms for easier analysis of the faulty system. They generate various test waveforms like sine, triangular and square which are useful in digital testing, HI-FI equipment, electronic workshop, colleges and research work in laboratories. Depending on the area of application, function generators bear a variety of specifications. Ranges of frequencies is of primary interest. Some applications require functions up to just above audio, these include audio filter applications. Some require higher frequencies, examples in amplitude modulation. 1.2 STATEMENT OF THE PROBLEM It is required to come up with a function generator, ...... impedance of the integrator should be at least ten times as much as Zout of the op-amp quoted by the manufacturer which is typically less than 100Ω. THE INTEGRATOR [pic] Capacitance value is chosen as 100μF. By choosing a break frequency 1 decade lower than the lowest operating frequency we have, From f = 1 / 2π X RC 0.1 = 1 / 2π X R2 X 100μ R2 = 1 / 2π X 100μ = 15.9kΩ THE ATTENUATOR A 100KΩ variable resistor was chosen to simulate the attenuator. This would provide a thousandth of the maximum output amplitude with ease. This would be the one required and quoted in specification (6mV).
