Registed user can get files related to this applet for offline access.If java program did not show up, please download and install latest Java RUN TIMEor 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 + D | X = A sin( w t + B) |
| Y = A sin(w t + B) | default mode | Lissajou's figure |
| Y = C t + D | not 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.or

Topics containing links to people's sites are unneeded and contribute nothing as a whole, much like topics containing content like this one. You could have PMed a moderator and asked this same question and received the same Puppy Obedience Training response. Please do so in the future. |

Hi,
is it possible to download this applet?
I'm very interested, because I have to make an end work for school.
Greetz,
Jeanke

You will find "GET APPLET FILES' button at the end of the first posted message if you are a registered user and login to the system.
When you click the button, you will get files related to the applet in your email.

You shpuld have received in your email account.
However it was written many years ago with JDK1.0.2.
You might need to make some change to make it works with current verison JDK.

Could you let me know why you need the source code?

You should have received the source code now. However, could you tell me what you want to do with it?
Is there something need to be improved for the applet?
Let me know and may be I can help.

Hi, I was wondering...maybe you can help me with similar program. I need to make a program that calculates frequency of, how i say it in english, coinciding of two frequencies. For example if i had two frequencies in Hz: __|'''''|____|'''''|____|'''''|____|'''''|____ __|''''''''|______|''''''''|______|''''''''|____ I need a program that calculates frequency when both of them are '''''.  |

Are you talking about the beat product from two very close frequency signal?

Yes, i think so... i need a program that calculates frequency...if i put two frequencys ontop eachother, then in what frequency they are at same point (that is at max). |

Assume one of them is y=y0 *sin(w*t) another one is y=y0 *sin((w+dw)*t)
And add those two wave together y=y0 *sin(w*t)+y0 *sin((w+dw)*t)
Work out the mathematics, you can find out when you will get maximum (or minimum)...
