Types of Signal
There are two different types of signals: 1) Continuous-time signal and 2) Discrete-time signal.
- Continuous-time signal (CTS): It is a signal that is specified for all values of time. It is denoted by x(t).
- Discrete-time signal(DTS): It is a signal that is specified only for a certain value of time. It is denoted by x[n].
Difference Between Time Shifting, Time Scaling and Time Reversal
When we talk about different types of operations performed on a signal, the concepts of shifting, scaling, and reversal come out. They are the basic operations that must be understood for signal sketching or simply drawing a signal. These operations not only help you sketch, but they help you understand the behavior of signals under different operations. But sometimes, they are a little bit confusing and it is difficult for us to differentiate between these terms. In this article, we will discuss these three terms in detail and we will also discuss some basic differences between them, that will help you understand better.
