ECE444 Advanced Digital Design
Assignment 6
- Download the example project audio1.
Build the project, connect the output (from line-out plug) to an
oscilloscope and the input (line-in plug) to the function generator.
Use a Y-connector from the function generator to display the input on
the oscilloscope.
Set the input to various waveforms (frequency about 500 Hz) and
capture the input and output signals from the oscilloscope.
- Set the input to
a sine wave of various amplitudes and capture the digitized values using SignalTap II.
Plot the amplitude in counts versus the amplitude in volts.
- Download the example MATLAB files
audio.zip.
Using the MATLAB laboratory instrument control program and the
audio1 project, measure and plot the frequency
response of the system by finding the voltage amplitude ratio
(Vout/Vin) and phase over the frequency range where the amplitude
ratio is above 0.1.
- Follow the guidelines in
DSP examples (ECE575 Cornell University)
and generate a bandpass filter. Have your filter specifications and
target filter type approved by the instructor.
