In this laboratory, you will learn how to use the
which is based on the graphical programming language G.
You will then write a
program to acquire, display, and save an external voltage signal.
As an extra credit exercise, you
will investigate the effects of undersampling.
is a programming language just like other programming languages, such as C,
Basic, or Pascal, but
In text-based programming languages, you are as
concerned about the code as you are about what you are trying to do; you must pay close attention
to the syntax (commas, periods, semicolons, square brackets, curly brackets, round brackets, etc.).
is much more user-friendly —it uses icons to represent subroutines, and you wire these
icons together in order to define the flow of data through your program.
It is sort of like flow-
charting your code as you are writing it—and the net effect is that you can write your program in
a lot less time than if you did it in a text-based programming language.”
