Select one:
a. 1z−a

b. zz+a

c. zz−a

d. -zz−a​

Answer 1

Answer:

Until now we have assumed that time is continuous.  In other words, time can take on any value, and this is generally true of linear physical systems involving components as capacitors, masses, thermal resistances...  However, computers are increasingly being integrated into systems.  For the computer, time is not continuous, it passes in discrete intervals.  So whenever a computer is being used, it is important to understand the ramifications of the inherently discrete nature of time.  As with the Laplace Transform, we will assume that functions of interest are equal to zero for time less than zero.
