Another class of design methods is based on the statistical modeling of spectra; and in these methods, the least-squares error (LSE) criterion is employed. These methods are especial

Such discrete-time systems can be realized by, for example, switched-ca-pacitor circuits where the amplitudes are represented by voltage or charge and are thus continuously variable. However, the vast majority of discrete-time systems are realized by digital computers or hard

The , Transform, and output of a discrete-time system involves multiplication of the appropriate . transforms, rather than convolution as for the signals themselves. Poles and zeros can be defined from the . transform and have the same useful role and intuitive appeal as for continuous-time systems. And finally, th

Each has its own particular advantage in certain derivations and calculations. We have previously introduced and used the impulse response in chapter 2; in this chapter we will define and stud
