ABSTRACT
Having introduced a variety of popular windows in the continuous-time-domain in Chapter 3, we will now discuss their discrete-time counterparts, so that they can be implemented in several digital signal processing applications. To have a wider choice, we have also included few more windows in this chapter, the characteristics of which were not discussed in Chapter 3. We have also defined a number of parameters that will enable the user to select appropriate windows, depending on the application. Finally, based on the parameters computed, we compare the performance of the discrete-time window functions. Section 5.1 presents different classes of window functions. Discrete-time windows are discussed in Section 5.2. Different figures of merit, which will enable proper window selection, are defined in Section 5.3. The concept of time–bandwidth product is introduced in Section 5.4. Finally, Section 5.5 gives applications of windows in finite impulse response filter design and power spectral estimation.
