Abstract : Oscilloscopes are used for displaying and analyzing electrical signals. Basic electrical components or circuit modules can be tested for their working. In today’s world, PC based measurements have become more affordable and easy to use, thus opening the door for “virtual instrumentation”. This paper describes about developing a PC based virtual oscilloscope. Data acquisition part has been done using sound card as A/D converter and a software manager was developed for processing the signals with the help of SCILAB. The PC based virtual oscilloscope can be used by undergraduate students for analyzing signals without the use of traditional oscilloscope.
