Explanation:

The output signal Vout(t) is in the form

Vout(t)=Acos(200πt + θ₁) + Bcos(400πt + θ₂)

The input signal Vin(t) is given as

Vin(t) = 10cos(200πt + 30°) + 20cos(400πt + 45°)

The output signal Vout(t) is found by

Vout(t) = H(f) × Vin(t)

Where H(f) is the transfer function at various frequencies and Vin(t) is the input signal.

H(200) = 1 ∠−20°

H(400) = 3 ∠−40°

converting the input signal into phasors

10cos(200πt + 30°) = 10 < 30°

20cos(400πt + 45°) = 20 < 45°

Vout(t) = H(200)×10cos(200πt + 30°) + H(400)×20cos(400πt + 45°)

Vout(t) = (1 ∠−20°)×10cos(200πt + 30°) + (3 ∠−40°)×20cos(400πt + 45°)

Vout(t) = (1 ∠−20°)×(10 < 30°) + (3 ∠−40°)×(20 < 45°)

Multipy the magnitude and add phase angles together

Vout(t) = (1×10 ∠−20° + 30°) + (3×20 ∠−40° + 45°)

Vout(t) = 10 ∠ 10° + 60 ∠5°

Vout(t) = 10cos(200πt + 10°) + 60cos(400πt + 5°)

Comparing it with the general form

Vout(t)=Acos(200πt + θ₁) + Bcos(400πt + θ₂)
