To perform the Interpolation process from a given discrete sequence in TMS320C5505 KIT
"Interpolation", in the DSP sense, is the process of upsampling followed by filtering. (The filtering removes the undesired spectral images.) As a linear process, the DSP sense of interpolation is somewhat different from the "math" sense of interpolation, but the result is conceptually similar: to create "in-between" samples from the original samples. The result is as if you had just originally sampled your signal at the higher rate.
"Upsampling" is the process of ( increasing the sampling rate of a signal ) inserting zero-valued samples between original samples to increase the sampling rate. (This is called "zero-stuffing".) Upsampling adds to the original signal undesired spectral images which are centered on multiples of the original sampling rate.
The upsampling factor (commonly denoted by L) is usually an integer or a rational fraction greater than unity. This factor multiplies the sampling rate or, equivalently, divides the sampling period. For example, if compact disc audio is upsampled by a factor of 5/4 then the resulting sampling rate goes from 44,100 Hz to 55,125 Hz.
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 Interpolation process was performed and displayed the results in console window.
