If a sequence is causal then ROC is (where a is any number)
-
X and Y are two random variable and Z = X + Y. Let σx2, σy2 and σz2 be variance of X, Y and Z. Then
-
Consider the following sets of values of E, R and C for the circuit in the given figure.
- 2 V, 1 Ω, 1.25 F
- 1.6 V, 0.8 Ω, 1 F
- 1.6 V, 1 Ω, 0.8 F
- 2 V, 1.25 Ω, 1 F

Assertion (A): The conditions under which it is possible to write Fourier series of a periodic function are called Drichlet conditions.
Reason (R): If f(t) = - f(- t), it is refereed to as odd symmetry.

L[c1f1(t) + c2f2(t)] =
