ABSTRACT

This chapter introduces block pulse function as well as other related piecewise constant orthogonal basis functions such as Haar functions, Walsh functions, generalized block pulse functions, non-optimal block pulse functions, pulse-width modulated block pulse functions, delayed unit step functions, and sample-and-hold functions in the form of a brief review. After the introduction, applications of block pulse functions in the area of systems and control are discussed. At the end of this chapter, more than sixty useful references are given. Also, nine study problems are included for the benefit of the readers.
