A) According to the circuits in fig.1.a and 1.b. 1) For each circuit, derive the sinusoidal steady-state transfer function. (Both magnitude and phase). 2) Assume that the input is (A*sinwt) sinusoidal wave. Find the input frequency where the output voltage will be 45 out of phase, than the input voltage. Calculate the amplitude of the output voltage at this frequency. 3) Find the input frequency where the amplitude of the output voltage is 4 of the amplitude of the input voltage. ( Calculate output frequency for this frequency) Velt) Vt) V.(t) Figure 1.a Figure 1.b
