Realization of digital linear systems
For the design of digital filters, the system function H(z) or the impulse response h(n) must be specified. Then the digital filter structure can be implemented or synthesized in hardware/software form by its difference equation obtained directly from H(z) or h(n).Each difference equation or computational algorithm can be implemented by using a digital computer or special purpose digital hardware or special programmable integrated circuit. In order to implement the specified difference equation of the system, the required basic operations are addition, delay and multiplication by a constant. A chosen structure determines a computational algorithm. Generally, different structures give different results. The most common methods for realizing digital linear systems are direct, cascade and parallel forms, and state variable realizations.
