Digital Oscilloscope 2.1
Display and Analysis of Waveform Patterns
1. Welcome to Digital Oscilloscope
This software oscilloscope enables you to use your Macintosh as an oscilloscope
and as a frequency meter.
To run this application, you need sound input hardware and an appropriate
sound driver, Systems Software 7.0 or later, and one megabyte of RAM.
Version 2.1 supports two-channel sound input, 16-bit amplitude resolution,
and color traces.
Digital Oscilloscope 2.1 is freeware.
If you are using this software you should not forget to give me a feedback
about your use of the program. Send your comments, suggestions, and bug reports to:

1.1 Introduction
Oscilloscopes and frequency meters are some commonly used instruments in
electronic engineering. If you intend to use such instruments in the
audible spectrum, there is a good reason to consider using your Macintosh
together with this application.
Oscilloscopes permit a visual examination of electrical phenomena. Usually,
they display the amplitude of a signal as a function of time. An important
feature common to all oscilloscopes is the triggering mechanism. The trigger
is used to determine at what time the display of the signal has to start.
The triggering feature is especially useful for the examination of periodic
electrical phenomena, which take place too fast for the eye to follow.
In addition, the oscilloscope may be used to study any variable that can
be converted into electrical potentials.
For periodic phenomena, the number of cycles that occur over a given time
period is of major interest. This is the primary use of the frequency meter.
