Valid for year : 2018
TSEI07 Digital Filters, 6 ECTS credits.
/Digitala filter/

For:   EL  


Prel. scheduled hours: 56
Rec. self-study hours: 104

  Area of Education: Technology

Main field of studies: Electrical Engineering

  Advancement level (G1, G2, A): G2

The aim of the course is to give the theoretical basis for analysis and synthesis of digital filters and basic knowledge about implementation of digital filters in hardware and software. After the course, the student is expected to be able to:
  • synthesize FIR and IIR filters, especially wave digital filters,
  • analyze finite wordlength effects in digital filters,
  • synthesize digital systems with several sampling frequencies using interpolation and decimation,
  • analyze computational properties of recursive algorithms,
  • use computer programs to solve problems within digital filtering.

Prerequisites: (valid for students admitted to programmes within which the course is offered)
Basic courses in circuit theory and linear systems.

Note: Admission requirements for non-programme students usually also include admission requirements for the programme and threshhold requirements for progression within the programme, or corresponding.
