The ,-Transform,analysis. Extending the set of basis signals at other than the unit-circle, results in the capability to analyze a large set of unbounded signals, which is very useful in stability analysis of systems. Examples of deriving the .-transform of useful signals are given. The properties of .-transform, w

Finite Impulse Response Filters, the FIR filter is designed and analyzed. The FIR filters can be designed easily with linear-phase response, which is desired in a variety of applications such as image processing. Two major types of methods are used in designing FIR filters. In the window method, the impulse response of the desired

Infinite Impulse Response Filters,es less number of coefficients for the same specification. However, it is susceptible to instability. This type of filters is developed from the basic resistor–capacitor lowpass filter for clear understanding of the filtering process. The idea is that the transfer functions of families of analog fil
