Unit Step Signal
Introduction: This section explains the unit step signal and also derives the unit step signal in the following way. The unit step signal: A well known discontinuous function is the unit step function u 0 * (t) which is defined as It is also represented by the waveform of Figure given below In the waveform of Figure above, the unit step function u 0 (t) changes abruptly from 0 to 1 at t = 0. But if it changes at t = t 0 instead, it is denoted as u 0 (t-t 0 ) . In this case, its waveform and definition are as shown in Figure given below If the unit step function u 0 (t) changes abruptly from 0 to 1 at t = -t 0 , it is denoted as u 0 (t t 0 ) . In this case, its waveform and definition are as shown in Figure given below.
