The Virtual C.R.O. program simulates a Cathode Ray Oscilloscope (C.R.O.). It has been designed for engineering students to study various waveforms using a C.R.O.-like interface, since the actual C.R.O. and the circuits they are studying may not always be available to them due to limited laboratory access.Please note that this is merely a software simulation, and the waveforms that the program displays are software-generated (using programmed mathematical expressions). This program could be used as a simple interface to observe any waveform (typically the theoretical output of some circuit), to study various C.R.O. effects and experiments, or even to learn how to use a C.R.O. The virtual C.R.O. has 5 input channels. What Т‘signalsТ‘ are Т‘connectedТ‘ to each channel is defined by the Т‘experimentТ‘ you select, and its parameters. The program includes a set of common experiments; you can add your own by modifying the source code and re-compiling the program.
