The Fourier TransformWe have seen that if .(.) is a function supported on an interval [−.] for some . > 0, then .(.) can be represented by a Fourier series as

Signals and SystemsIn the previous chapter, we considered piecewise continuous functions with period 1 and showed that it is possible to represent such functions as an infinite superposition of exponentials ..(.) = .., . ∈ .. Each such exponential has period 1/. and hence completes . cycles per unit length (which we can interpret as measuring time).

Biorthogonal WaveletsIn Chapter 2, we considered the notion of orthonormal bases that have infinitely many elements and that can be used to represent arbitrary .. functions. In this section, we will consider nonorthogonal systems with many of the same properties. Such systems are referred to as ..
