To perform the Decimation process from a given discrete sequence in TMS320C5505 KIT
Decimation is the process of filtering and downsampling a signal to decrease its effective sampling rate. The filtering is employed to prevent aliasing that might otherwise result from downsampling. Finally, "Decimation" is the process of reducing the sampling rate. In practice, this usually implies lowpass-filtering a signal, then throwing away some of its samples.
"Downsampling" is a more specific term which refers to just the process of throwing away samples, without the lowpass filtering operation. Throughout this FAQ, though, we'll just use the term "decimation" loosely, sometimes to mean "downsampling".
The downsampling factor (commonly denoted by M) is usually an integer or a rational fraction greater than unity. This factor multiplies the sampling time or, equivalently, divides the sampling rate. For example, if compact disc audio at 44,100 Hz is downsampled to 22,050 Hz before broadcasting over FM radio, the bit rate is reduced in half, from 1,411,200 bit/s to 705,600 bit/s, assuming that each sample retains its size of 16 bits. The audio was therefore downsampled by a factor of 2
1. Open Code Composer Studio v4 .
2. In WorkSpace Launcher.
3. FILE ⇒ NEW ⇒ CCS PROJECT
4.FILE ⇒ NEW ⇒ SOURCE FILE
5. Paste the following board library files in workspace location.
6. Paste the Linker file in the project location.(linker file is available in cd)
Note: Those folders and linker file are availble at cd.
7. PROJECT ⇒ PROPERTIES ⇒ C/C++ BUILD ⇒ BASIC OPTION
8. FILE ⇒ NEW ⇒ TARGET CONFIGURATION FILE
9. In C/C++ Project window, Right click the project ⇒ REBUILD PROJECT.
10. Connections :
11. TARGET ⇒ DEBUG ACTIVE PROJECT.
12. TARGET ⇒ RUN.
13. Output is displayed at Console Window.
14. TARGET ⇒ HALT.
Thus, the Decimation process was performed and displayed the results in console window.
