What is time scaling of discrete time signals?
What is Time Scaling? The process of multiplying a constant to the time axis of a signal is known as time scaling of the signal. The time scaling of signal may be time compression or time expansion depending upon the value of the constant or scaling factor.
What is meant by time scaling?
Time scaling or time stretching is the process of slowing down or speeding up an audio signal without changing the pitch. The applications of time-scaling are numerous with an example given above as well as reading text for the blind, and learning a foreign language.
What is the difference between CTS and DTS signals?
Discrete-time signals are defined at the discrete moment of time and the mathematical function takes the discrete set of values. Continuous-time signals are characterised by independent variables that are continuous and define a continuous set of values.
How do you signal a time scale?
A signal x(t) is scaled in time by multiplying the time variable by a positive constant b, to produce x(bt). A positive factor of b either expands (0 < b < 1) or compresses (b > 1) the signal in time.
