What is a cro???
I do not know how to create a simulation which can input signal via a sound card!
I just search with google:
There are some library available: e.g. http://java.sun.com/docs/books/tutorial/sound/index.html

So it is possible to input signal via a sound card!

is Cathode-Ray Oscilloscope the CRO ?

i thought i saw one before here

This java applet shows the basic functions of an oscilloscope.
The oscilloscope is an electronic instrument widely used in making electrical measurements.
The main component of the oscilloscope is the cathode ray tube (CRT).
The CRT is a vacuum tube in which electrons are accelerated and deflected under the influence of electric field. The electrons are deflected in various directions by two sets of plate placed at right angle to each other in the neck of the tube.
Signal for the horizontal deflection plate (X-axis) is generated by the scope
It mathematic form is Fx(t)= C t + D (default)
C : time scale
D : horizontal offset
The external signal (need to be measured) is applied to the vertical deflection plate (Y axis).
The default form for this java applet is Fy(t)=A sin(w t + B)
    You can change X or Y axis signal to either kind of signal.

It can be operated in different mode



X = C t + DX = A sin( w t + B)
Y = A sin(w t + B)default modeLissajou's figure
Y = C t + Dnot supported for an oscilloscope


For parameter B please enter value in degree.
Click within one of the knobs and drag the mouse button clockwise/countercolockwise to change values for Time/Div, Volt/Div , yOffset and xOffset.
