This exercise introduces the DSP hardware and associated software used in the course. By the end of this module, you should be comfortable with the basics of testing a simple real-time DSP system with Code Composer Studio, the TI DSP c55x debugging environment. First you will connect the laboratory equipment and test a real-time DSP system with provided code to implement an eight-tap (eight coefficient) finite impulse response (FIR) filter. With a working system available, you will then begin to explore the debugging software used for downloading, modifying, and testing your code. Finally, you will create a filter in MATLAB and use test vectors to verify the DSP's output.

Introduction

This exercise introduces the work-flow environment for developing real-time signal-processing systems, which consists of three major components:

  1. hardware I/O tools (i.e., a function generator and oscilloscope), which are valuable for testing the functionality of a real-time DSP system,
  2. a software debugging environment, such as Code Composer Studio (CCS), which is used to write, download, execute, and debug DSP code,
  3. a high-level development environment, such as MATLAB, which is used to verify computational correctness, and explore and debug conceptual issues.

The DSP task in this exercise will be to implement a pre-written eight-tap (eight coefficient) finite impulse response ( FIR ) filter, verifying correctness using the hardware I/O tools, along with MATLAB test vectors.

Lab equipment

This exercise assumes you have access to a laboratory station equipped with a Texas Instruments TMS320C5510A-200 digital signal processor chip mounted on a Spectrum Digital TMS320VC5510 evaluation board. The DUAL3006, a daughtercard produced by Educational DSP, is mounted on the external peripheral interface of the board to enable four-input/four-output capability. The evaluation module should be connected to a PC running Windows and will be controlled using CCS v5.0. We will be using a 48kHz sample rate.

If you are not using Code Composer Studio v5.0, the instructions on this page do not apply. Please see the Digital Signal Processing Laboratory (ECE 420 55x) Collection for instructions for version 4.0 and earlier.

In addition to the DSP board and PC, each laboratory station should also be equipped with a function generator to providetest signals and an oscilloscope to display the processed waveforms.

Step 1: connect cables

Use the provided BNC cables to connect the output of the function generator to the input of the DSP evaluation board, and the DSP outputs to the oscilloscope, as shown in [link] .

Example hardware setup

The actual channel ports may differ than what is shown in the illustration. Read the labels on the evaluation board!

With this configuration, you will have only one signal going into the DSP board and two signals coming out.The output on channel 1 is the filtered input signal, and the output on channel 2 is the unfiltered input signal.This allows you to view the raw input and filtered output simultaneously on the oscilloscope. Turn on the functiongenerator and the oscilloscope.

sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul
hmm
Abhi
is it a question of log
Abhi

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world

can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
