Low cost design of a PC based integrated system for signal measurement and generation using microcontroller

This paper presents a low cost device for both measurement and generation of electrical signal used in any basic electrical experiment. The total project has one hardware unit based on a microcontroller which can receive and generate analog signal by the command of PC software and the PC software interface which is capable of displaying the measuring signal, send command for desired signal generation and export data to other simulation software. This PC software is also capable of doing different simple analysis and export data to software like MATLAB. The performance of the device is satisfactory and there are many scopes to enhance its features in the future.
