  • Submit one page description of project lab (topic and team) by May 14.
  • Ideas for fifth lab, "project lab"
    • Digital down conversion (especially quarter-rate down conversion: fs=4*fc)
    • Wavelet transform, re-using block processing from Lab 4.
    • Audio effects
    • Re-write FIR filter to optimize clock cycles DSP DesignLine
    • Re-write Adaptive FIR filter to optimize clock cycles using LMS command
    • Digital demodulation of AM, FM or PM signals
    • Others (see left-hand column, project labs)
• FFT spectrum analyzer (lab 4): prelab due in lab, May 8 or 10.
  • (Links to lab manual sections given below.)
• Weeks 5 and 6 in laboratory (April 24--May 7): IIR filter exercise.
  • IIR prelab due in lab, April 24 or 26.
  • Lab 3: IIR prelab
  • Matlab code for scaling cascade realization
  • Lab 3: IIR Lab exercise
• LMS adaptive FIR filtering
  • Lab 2: Adaptive FIR Filtering
  • For prelab on LMS adaptive FIR filter, come to lab prepared with the assembly language commands necessary to insert the weight update equation into your FIR code.
• "Lab 1": FIR filtering
  • Lab 1: FIR Filtering
    (See asm file for hints on part 2.)
    Note: part 3 may be submitted at beginning of lab next week (April 16-19) to receive full credit. To demo part 3, come prepared with the few lines of assembly code already written: implement and exaplain your result.
