Answer: Option C Explanation: value of
x(n) = d(n) impulse response. |
42. | Find the Fourier transform of the half cosine pulse as shown below : |

Answer: Option B Explanation: The given signal can be expressed as multiplication of x_{1}(t) and x_{2}(t) as shown below. where A = 2, T/2 = 0.25 => T = 0.5 ∴ x(t) = x_{1}(t) x x_{2}(t) => X(f) = X_{1}(f) * X_{2}(f) Now X_{1}(f) = [δ(f - f_{0}) + δ(f + f_{0})] = [sin c [T(f - f_{0})] + sin c[T(f + f_{0})]]
Now, A = 2, T = 0.5 and f_{0} = = 1 => X(f) = 0.5[sin c (0.5(f - 1)) + sin c (0.5(f + 1))]. |
43. | The q-v relation of a capacitor is v = 1 + q + q^{x}. Find the amount of energy required to charge this capacitor from q(t_{0}) = 0 to q(t) = 5 C. |

Answer: Option C Explanation: Given equivalent circuit is Norton's equivalent circuit V = 8 - 4I Put V = 0I = I_{N} = 2 A Put I = 0 V = V_{TH} = 8 V . |
45. | If the open-loop transfer function is a ratio of a numerator polynomial of degree 'm' and a denominator polynomial of degree 'n', then the integer (n - m) represents the number of: |
