Discrete Linear Systems,ass suspended by a linear spring and, possibly, a viscous damper (Figure 1–1a). Historically, however, the mathematical pendulum (Figure 1–1c) represented for centuries the most common paradigm of an oscillator, which could be assumed to be linear, at least within adequate limitations.
