Abstract

Cathode Ray Oscilloscope is most versatile and widely used instrument in the sciences, medicine, engineering, and telecommunications industry. The Cathode Ray oscilloscope is used for variety of purpose such as detecting wave form, frequency, and time period. A signal generator is a device which produces simple repetitive waveforms and such devices contain an electronic oscillator, a circuit that is capable of creating a repetitive waveform. The most common waveforms are sine wave, saw tooth, step pulse, square, and triangular waveform. The goal of this project is to design a signal generator and a digital oscilloscope with 20 kHz bandwidth. The signal generator and digital oscilloscope that is used in laboratory cost ten to twelve thousands. The motivation of this project is to produce an affordable, easy to make a signal generator and an oscilloscope for students or other engineers who cannot afford to buy a manufacturer’s oscilloscope. The project consists of two parts: Signal generator and Digital Oscilloscope. A single ARM7 controller is used in the project which acts like master brain of the system. At a time a single functionality works and is based on mode selected by the user.
