Digital Signal Processing Education Kit

Teach the theory and practice of managing digital signals that come in from a variety of sources, which is crucial, given the explosion of digital data in today’s world.  While many DSP courses use software simulation packages, or expensive development kits, this course is based on low-cost, Arm-based hardware boards and Arm software licenses, allowing students to practice theory with advanced hardware.

Kit specification:

  • A full set of lecture slides, ready for use in a typical 10-12-week undergraduate course (full syllabus below)

  • Lab manual with solutions for faculty. Labs are based on low-cost hardware platforms (donated by partners and subject to availability) powered by Arm Cortex-M-based microcontrollers that enable high performance yet energy-efficient digital signal processing, and use the industry-standard Keil MDK-Arm application development tool.
  • Prerequisites: Basic C programming, elementary mathematics.

Course Aim

To produce students who can design DSP systems and create commercially-viable audio applications using high-performance and energy-efficient Arm processors.

Learning Outcomes

  • Knowledge and understanding of
    • DSP basic concepts such as sampling, reconstruction and aliasing
    • Fundamental filtering algorithms such as FIR, IIR, FFT
