Integral and summation transforms play a foundational role in analysis of linear time-invariant (LTI) filters. Laplace, Z, Fourier and wavelet transforms give users and filter designers the necessary tools to filter, analyze and visualize signals and systems in the frequency and time-frequency domains.
