- Hello! Here I present the english and german version of OSCILLOGRAPH.
- As the name indicates, the program is an emulation of an oscillograph.
- You know, these machines with lots of knobs and buttons, and a flourescent
- screen. Perhaps You have seen one on school, and displayed some dancing
- Lissajouz figures with it. Or You even use one for technical purposes.
-
- Now, if You lack an expensive oscillograph, try to use this program. It´s
- perfect for demo purposes (e.g. You can easily produce all kinds of
- Lissajouz figures and more by using the internal oscillation generators),
- and even can display real signals (when You have an AD converter or an
- audio digitizer).
-
- The first idea to write this program lies several years back, when on
- school was shown an oscillograph displaying dancing Lissajouz figures.
- One of my classmates wrote a BASIC program to plot those figures on a
- home computer. It needed some seconds to create one figure. I wanted to
- do better and wrote a 6502 assembler program on good old C64 which could
- produce nearly 20 figures in one second!
-
- Years later, when I have bought my Amiga, I translated my program to
- 68000 assembler and redesigned it to look like an oscillograph. I added
- an editor for internal oscillations and implemented a complete function
- plotter. Then I got an audio digitizer and extended my program to use
- it for reading external signals.
-
- Now I finally have translated the program into English, and submit it to
- the Fred Fish library. Both versions, the original german and the translated
- english one, are included on this disk. The german version uses PAL-graphics
- (256 lines), so it won´t run properly in "NTSC-countries" like the USA, and
- You have to use the english version, which I wrote with 200-line-graphics.
-
- For more detailed information about the program type the ".doc"-files which
- can be found along with the programs themselves in the directories
- "Oscillograph/German" and "Oscillograph/English". The directory
- "Oscillograph/Oscillations" contains a basic set of oscillations for use
- in any version of OSCILLOGRAPH.
-
- ComplexPlotter was written under Kickstart 1.3 in assembler, but it should
- run under 2.0 or higher without problems. It needs the MathTrans.library.
- If you don´t have a digitizer which is compatible with mine, you can´t
- display external signals, but still use all other segments of my program.
