Log domain filtering is a very new area of active filter design. As a result, there are no generally accepted design procedures. The discussion in this chapter has therefore centred on familiarising the reader with the basic ideas and concepts related to this new idea. An attempt has been made to summarise several perspectives on the design of these filters, with the intent to give the reader an ability to not only appreciate how to go about designing log domain filters, but also access the literature for more information and perspective.
