[#116] For a periodic signal $$vleft( t
ight) = 30sin 100t + 10cos 300t + 6sin left( {500t + {pi over 4}}
ight),$$ the fundamental frequency in rad/s is
Correct Answer
(A) 100
[#117] The final value theorem is used to find the
Correct Answer
(A) Steady state value of the system output
[#118] The impulse response h[n] of a linear time-invariant system is given by h[n] = u[n + 3] + u[n - 2] - 2u[n - 7], where u[n] is the unit step sequence. The above system is
Correct Answer
(A) Stable but not causal

ight)left( {s + 3}
ight)}}$$ xa0 is
Correct Answer
(A) 2e -t - e -3t
