11.
The inverse Laplace transform of 1/(s - a)2 is
12.
If f(t) = sgn(t), F(jω)
13.
If xk = 0 for k < 0 and = 2k for k ≥ 0 X(z) = z/(z -2).
14.
Assertion (A): If an event A can happen in m ways and another event B can happen in n ways, both can happen in mn ways.
Reason (R): Two events are mutually exclusive if happening of either precludes the occurrence of other.
15.
Assertion (A): In the curve 
, a high value of h indicate a high peak and rapid fall in the curve.
Reason (R): If the number of ways in an event may result can be analysed into a successes and b failures, each equally likely to occur, the probability of success in a single trial is
