Independent Project Thesis in Electrical Engineering: Design and implementation of digital filters
2019 (English)Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
Abstract [en]

This thesis describes and discusses design and implementation of digital filters inembedded systems. Digital filters provide great flexibility where an interchangeablefilter is needed and real valued components are limited. Common sampling problemssuch as aliasing and reconstruction are discussed and solved using analog filters.A circuitry is constructed to interact with the embedded system according to itsspecifications. Digital filter theory is reviewed and applied in both IIR (Infinite ImpulseResponse) and FIR (Finite Impulse Response) filters. Design methods used arewindow method for the FIR filter and zero-pole placement for the IIR filter. Thefilters are implemented in c code on an embedded system named UC3-A3 AVR-boardfrom Atmel. The complete system is effectively used to filter a music piece fromunwanted interference and noise with real-time computing.
