Files
The data file formats used by most
application software includes "data context" information. For
example, a word processor file includes not only the codes for the actual text,
but also a code to specify the font. However, your DSP data files consist of
just...well...data. Raw data doesn't have any meaning until you give it a
context. The most obvious "data context" information encountered in
DSP applications is sampling rate. Knowing the sampling rate lets
ScopeDSP™ not only show an accurate X-Axis on its Time Data plot, but more
importantly, lets it show an accurate X-Axis on the Frequency Data plot.
Unfortunately, the file of sample data you acquired from your A/D converter
doesn't have any embedded context. And the data produced by your simulation
probably doesn't either.
That's why ScopeDSP packages data context information in a separate file.
ScopeDSP creates "Project Files" to store data context information
including sampling rate, time/frequency units, decibel reference, and even the
default file directory! ("Pinch me!") You simply select the options
you want via the user interface and then save a Project File. When you want to
recall a set of context options, you just load a new Project File. In this way,
you can easily switch data contexts as you analyze the data produced at
different stages of your DSP system.
The separation of data into the "raw data files" produced by your
other DSP tools and the "Project Files" generated by ScopeDSP is a
very practical way to reduce manual entry of data context information. As you
use ScopeDSP, you will find that you will develop a small set of project files
to use with each of your DSP projects.
