Design And Implementation Of A Signal Generator Using Microcontroller

This thesis discusses the development process and the common features of a microcontroller based signal generator which allows the user to select a waveform type (sine, square, sawtooth and triangle) and to select the waveform frequency and amplitude.Signal generator that generates different shapes of waveforms over a wide range of frequencies, is an important instrument in testing and operating different kinds of electrical equipments. It can provide a wide range of controlled amplitudes, and maintain constant amplitude as the frequency is varied. It is widely used in engineering applications especially in control field. This thesis discusses the development process and the common features of a microcontroller based signal generator which allows the user to select a waveform type (sine, square, sawtooth and triangle) and to select the waveform frequency and amplitude. Many hardware and software tools are involved in the design of the signal generator. Microcontroller is used to generate the signal and to display the frequency and the amplitude of the generated signal
