Basic Signal Operations Performed on Time
Basic operations on independent variable time are also known as Time transformations. In which we manipulate or modify the time axis of a signal by applying mathematical operations to its independent variable denoted as ‘ t ‘ while the amplitude of the signal is constant.
There are three basic time domain operations, which are
- Time-Shifting of Signals
- Time-Scaling of Signals
- Time-Reversal or Reflection of Signals
Basic Signal Operations
Basic signal operations are nothing but signal manipulation or modification tools that are used in signal processing and analysis. It helps to understand the signals in different situations. These operations allow the modification and enhancement of signals for specific applications.
In this article, we will discuss the basic signal operations and understand different operations related to the time and amplitude of the signal. In time transformations, we will cover time scaling, time shifting, and time reversal, and in amplitude transformations amplitude scaling of signals, amplitude reversal of signals, addition of signals, multiplication of signals, differentiation of signals and integration of signals. We also cover various advantages, disadvantages and applications of time and amplitude transformations.
