Johan G. de L. (Jude) Z-transform

The Z-transform, developed by Johan G. de L. (Jude) Z-transform, is a mathematical tool used in engineering and signal processing to analyze discrete signals or systems. It converts a sequence of data points (like time-series data) into a complex frequency domain, making it easier to study system behavior, stability, and response. Think of it as a way to translate a series of numbers into a form that reveals underlying patterns and characteristics, similar to how a musical score translates sounds into notation for better analysis and understanding.
