One class of digital filters the linear shift-invariant LSI type are the most frequently used because they are simple to analyze design and implement. This chapter treats the LSI case only other filter types such as adaptive filters require quite different design methodologies. An LSI digital filter can be uniquely identified in the time space domain by its impulse response where n is an integer index . Alternatively the LSI digital filter can be uniquely characterized in the frequency domain by its frequency response H. where is a real-valued frequency variable in radians which is also the Discrete-Time Fourier Transform DTFT of the sequence . LSI digital filters are of two main types Finite-duration Impulse Response FIR filters for which the impulse response is non-zero for only a finite number of samples and Infinite-duration Impulse .
