Digital frekvensutjämning för in-ear hörlurar implementerat i FPGA
2010 (Swedish)Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesisAlternative title
Digital frequency equalization for in-ear earphones implemented in FPGA (English)
Abstract [sv]

Detta är en rapport för ett 15hp examensarbete på Linköpings Tekniska Högskola. Projektet syftar till att implementera ett digitalt frekvensutjämningsfilter för audioapplikationer i ett Atmel DE2 FPGA utvecklingskort. Specifikt ska systemet användas till att korrigera ojämnheter i in-ear hörlurars frekvenssvar. Denna rapport är en beskrivning av systemets utformning och hur arbetet gick till väga.

Resultatet blev ett väl fungerande system och ett antal förslag på förbättringar.

Abstract [en]

This is a report for a 15hp thesis at the Institute of Technology at Linköping University. The project aims to implement a digital frequency-equalizing filter for audio applications in an Atmel DE2 FPGA development board. More specifically the system will be used to correct unevennesses in the frequency response of in-ear earphones. This report is a description of the design of the system and how the work on the project was executed.

The result was a well functioning system with suggestions on possible improvements.
