Signal transformation

Signal transformation is the process of changing a signal's form or properties to make it more useful or easier to analyze. It involves applying mathematical operations, such as Fourier or Laplace transforms, to convert signals from one domain (like time) into another (like frequency). This helps us identify patterns, filter out noise, or extract specific information. Think of it like changing the language of a message to better understand what it says—making complex signals clearer and more manageable for analysis or processing.
