Why the frequency domain analysis is important in signals and system?
The frequency domain representation of a signal allows you to observe several characteristics of the signal that are either not easy to see, or not visible at all when you look at the signal in the time domain. For instance, frequency-domain analysis becomes useful when you are looking for cyclic behavior of a signal.
What is frequency domain analysis?
Frequency Domain Analysis of Signals. □ In engineering and statistics, frequency domain is a term used to describe the analysis of mathematical functions or signals with respect to frequency, rather than time. □ The most common purpose for analysis of signals in the frequency domain is the analysis of signal properties ...
How do you know if two signals are correlated?
In words, we compute a correlation by multiplying two signals together and then summing the product. The result is a single number that indicates the similarity between the signals x[n] and y[n]. What values can C(x, y) take on, and what does this tell us about the signals x[n] and y[n]?
