In this topic, you study the Bounded and Unbounded Signals theory, definition & solved examples.
Bounded Signal
A continuous-time signal x(t) having finite value at any instant of time is said to be bounded signal i.e. if x(t) < M ; where M is the finite value for all time t. The bounded signal example with M=1 shown in Figure 1.
Figure 1: Bounded signal.
Unbounded Signal
A continuous-time signal x(t) having infinite value at any instant of time is said to be the unbounded signal. The unbounded signal example is shown in Figure 2.
