Cosiderations in the hardware implementation of digital filters

The availability of an increasingly wide variety of LSI logic circuit packages is making it possible to implement the digital filter signal processing algorithms directly in special purpose hardware. Whether or not such implementations (assuming they meet the signal processing performance specification) will be used or deemed practical depends on many considerations such as initial cost, reliability, power consumption, space requirements, interfacing requirements, and ease of maintenance. Each of these considerations has a very strong economic component and must be understood in any meaningful design.
