Abstract:A digital oscilloscope is the most commonly used device to observe and analyze an electrical signal. The device enables users not only to see the exact waveform of a desired signal, but also to easily obtain its wave properties such as amplitude, period, and wavelength. However, in some cases, a digital oscilloscope may not be available for use due to its size and high price. The purpose of this project is to overcome the problem by developing a program in MATLAB for observation and analysis of an electrical signal with only a PC. This can be accomplished by using the soundcard of a PC as an analog-to-digital converter to acquire an analog input signal. Then, using the data acquisition method of the MATLAB software, the converted signal will be made available for observation and analysis.
