The purpose of this lab is to familiarize students with the DSP development workstation in the signal processing lab by examining sampling, analysis, and reconstruction of continuous-time signals. Specifically, we will first look at sampling/reconstruction of continuous-time signals. We will then examine time- and frequency-domain displays. Finally, we will examine the importance of sampling frequency and its effects on aliasing.

Dsp workstation hardware list&Setup

Hardware: dell dimension 4550 pc with a pentium 4 microprocessor

    • Runs software to design/implement digital filters
    • Controls data acquisition and analysis
    • Communicates with the DSP board and/or soundcard
    • Edits/assembles/downloads code for the DSP chip on the DSP board

National instruments speedy-33

A self-contained, high-performance, programmable DSP board for signal processing applications. TheSPEEDY-33 comes equipped with a Texas Instruments DSP for high speed DSP calculations and Analog to Digital (A/D) and Digital toAnalog (D/A) converters for interaction with the outside world.

  • Specifications of the NI SPEEDY-33 are as follows:
    • Bundled with LabVIEW DSP programming environment
    • Includes a Texas Instruments VC33 floating point DSP processor
    • 13-ns Instruction Cycle Time
    • 150 Million Floating-Point Operations Per Second (MFLOPS)
    • 75 Million Instructions Per Second (MIPS)
    • USB interface used for connection to the PC
    • 16-bit stereo audio codec with two on-board microphones
    • Software-controlled adjustable sampling rate (8, 18, 24, 36, 44.1, and 48 kHz)
    • Eight memory-mapped LED’s and eight memory-mapped general purpose switch inputs
    • Serial Port, CompactFlash interface

Alternative option to NI Speedy 33:

Texas instruments 6711 dsk

  • Digital Signal Processing Board with PCM3003 Audio Daughter Card

The DSP board is responsible for the high-speed DSP calculations and the daughter card controls the A/Dand D/A conversion between the DSP board and the outside world.

  • Specifications of the DSP board and daughter card are as follows:
    • TI TMS320C6711 floating point DSP processor
    • Software-controlled adjustable sampling rate (8, 9.6, 12, 16, 24, and 48 kHz)
    • 16-bit stereo audio codec with two on-board microphones. A lowpass anti-aliasing filter at the input channel with a fixedcutoff frequency = 24 kHz

Software:

The software used in the lab is National Instruments LabVIEW DSP Module ; a block diagram-based graphical programming package for digital signal processing thatwill be used for: data acquisition, time domain data display, frequency domain calculation and display, filter implementation,convolution and correlation calculations, speech/signal modeling, and real-time filtering. Using LabVIEW DSP Module in conjunctionwith the LabVIEW Digital Filter Design Toolkit, the DSP board and the rest of the lab equipment will not only allow students toperform data acquisition, analysis, and filtering, it will also give them the ability to listen to the filtered output.
