Continuous-time System
Continuous-time System Continuous-time system is a system that describes the continuous-time input signals which transformed into a continuous-output signal. It can be represented by a block diagram shown in Figure 1 where x(t) and y(t) is the input and the output of the system, respectively. In studying continuous-time system, it takes into different physical orientations but then it ends up with similar mathematical relationships that comprise the whole scheme. In which, this system will consider the interconnections of the elements with one another. These orientations can either be exemplified by its time domain or by its frequency domain. x(t) y(t)

Figure 1 In order to understand this topic, continuous-time system comes into different classifications which are the following: * Linear and Nonlinear Systems
A system is linear if it follows the superposition principle. Also, it satisfies the additivity and homogeneity properties. Hence, if a system does not satisfy either of the two properties, it is said to be a non-linear system. * Time-varying and Time-Invariant Systems
A system is said to be
