Signal Wizard v.2. from UMIST

digital filters without headaches

Filter designing is a competence and taken very seriously in audio and measurement and control technology. The associated theory is massive, most textbooks concentrating on analogue approaches. Thanks to a tremendous increase in computing power of today’s chips, the art of filter design is shifting to the digital domain. However, converting an analogue filter to digital is not too easy, and that is why Manchester University have released Signal Wizard, a hardware/software suite to help the budding designer get to grips with DSP-based filters.
