Signals and Systems
In 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 e n (t) = e 2πint , n ∈ Z. Each such exponential has period 1/n and hence completes n cycles per unit length (which we can interpret as measuring time).
