Aim:
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.
