ABSTRACT
This study examines the process of designing a signal generator, to generate three types of wave forms which include sinusoidal wave, triangular wave, and square wave. Change the amplitude of the generated signal over a wide range. Measure both the frequency and amplitude of the selected signal and display them on the LCD. To carry out a computer aided simulation. This work is intended to build a low costing function generator from simple components available in laboratory, the frequency and amplitude of the generated signal can easily be tuned on a LCD, this eliminates the need for other devices, to measure or display the amplitude and the frequency of the signal. Typically, this signal generator type will produce waveforms or functions such as sine waves, saw tooth waveforms, square and triangular waveforms. But in this work, we are considering a square waveform. To achieve the objectives of the function signal generator project, hardware components and software tools are employed and used after they have been selected among other alternatives due to various reasons and circumstances. We also focus the design consideration that should be achieved on completion of this project, followed by a brief discussion about the overall circuit diagram, various blocks that constructs the function generator, and subsequently sections investigate these blocks by details.
