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.

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


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.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
