1.    TRUE/FALSE.  (15 marks) Write 'T' or ‘F’ if the statement is true or false.


1)    The unit step signal is equal to the time derivative of the unit ramp signal.
2)    The unit pulse function of duration T is called the delta function at T.
3)    The unit step signal is not a continuous signal because there is a discontinuity at the point of change
4)    A system that has memory cannot be non-causal
5)    A time invariant system cannot have memory



2.    Explain the ERRORS (10 marks)


Identify the two false statements in the previous subsection and explain shortly why they are false.
