At this stage, it is a standalone program that requires an X11 system to run, but a natural evolution path is reimplementing it in a form (for example, Java) suitable for interaction via the de-facto standard interface of the World Wide Web [3]. It should be noted that the input waveform is defined using C language; using different waveforms it is easily obtained by rewriting only one file and linking again the program. In Slave mode, the simulator does not permit the user (the student) to choose the input signal(s). In oscilloscope the signal is first amplified and applied to the vertical plate to deflect the beam vertically and at the same time a voltage that increases linearly with time is applied to the horizontal plate. Square wave also called pulse wave is a periodic waveform having an equal positive and negative pulse width.generally called as 50% duty cycle.
