Signals and Systems

  1. The joint pdf of random variable x and y is given by fxx(x, y) = ke– (ax + by) u(x).u(y)
    1. K = ab
    2. K =
      a
      b
    3. K =
      1
      ab
    4. K =
      b
      a
Correct Option: A

Fxy(x, y) =fxy(x, y)dx dy
-∞-∞

1 =ke–(ax + by) u(x).u(y)dy.dx
-∞-∞

1 =ke–ax.e–by.dydx
00

1 =
k
ab

or k = ab
