1. DSP
Mini-Projects

2. General Mini-Projects are based on Filter Design
All projects use FIR filter size N=128
Use MATLAB to Calculate coefficients
Use “Fir_C_Fixed” or “FIR” project template
Use BSL headers/libraries:
dsk6416.h
dsk6416_aic23.h
dsk6416_dip.h
dsk6416_led.h
dsk6416bsl.lib

3. Report Design and Implement Project (3hours)
Prepare Report Document including:
Short description of project
Final Program Listing
Frequency Response of Filters

4. P1 - 4 Switched LPFs Design 4 independent FIR LPFs:
Output Signal comes from one of the Filters
Use DIP-Switches to operate each one
Cut Frequencies:
Fc=400, 1600, 6400, Hz
Use Hamming Window
Fn=48KHz

5. P2 - 4 Switched HPFs Design 4 independent FIR HPFs:
Output Signal comes from one of the Filters
Use DIP-Switches to operate each one
Cut Frequencies:
Fc=200, 800, 3200, Hz
Use Hamming Window
Fn=48KHz

6. P3 - 4 Switched BPFs Design 4 independent FIR BPFs:
Output Signal comes from one of the Filters
Use DIP-Switches to operate each one
Band Limit Frequencies:
F = Hz
F = Hz
F = Hz
F = Hz
Use Hamming Window
Fn=48KHz

7. P4 - 4 Switched Stereo Filters
Design 2 LPF for Left + 2 HPF for Right:
Output Signal comes from one of the Filters
Use DIP-Switches to operate each one
Cut Frequencies:
Left Fc = 1600, 6400Hz
Right Fc = 1600, 6400Hz
Use Hamming Window
Fn=48KHz

8. P5 – 4-Band Freq Equalizer
Design Mix of 4 independent FIR BPFs:
Output Signal is a Sum of 4 Filters
Use DIP-Switches to operate each one
Band Limit Frequencies:
F = Hz
F = Hz
F = Hz
F = Hz
Use Hamming Window
Fn=48KHz

9. P6 – 4-Band Spectrum Analizer
Design Mix of 4 independent FIR BPFs:
Output Signal of each filter is integrated M=1024
Result of integration is compared with Threshold
Appropriate LED goes ON in case of result exceed Threshold
Band Limit Frequencies:
F = Hz
F = Hz
F = Hz
F = Hz
Use Hamming Window
Fn=48KHz
