Signals & Systems #07 | Unit Step u(t) & Ramp r(t) - CT and DT Definitions

Unit Step, Impulse & Signal Relations

Instructor: Dr. Süleyman Burak ÇELİK

In this first lesson of Lecture 4, we define the two most fundamental elementary signals: the unit step and the unit ramp, in both continuous-time and discrete-time. - Unit step u(t): piecewise definition, switching behavior at t=0 - DT step u[n]: stem plot, no ambiguity at n=0 - Unit ramp r(t) = t
