Question

Please answer number 1

1. Find the transfer function Voda)/Vin(a) for the circuit shown in Figure 1 of the lab (where complex frequency variable s jo can be substituted for ease of analysis.) Calculate values for R and C such that the phase shift between the output and input is zero for an input frequency of 10kHz. What is the amplitude ratio (gain) of the output to the input at this frequency. 2. The RC network in figure 3 of the lab can produce a phase shift of 180° at a desired frequency. Calculate this frequency for the network values given. (Recall a 180° phase shift corresponds to the transfer function Voutjo)/Vinja) being a real negative number.) What is the gain of the circuit? ratory Procedure: ● Build the following circuit using the component values determined in the prelab, with a sinusoidal input, observe the phase shift between input and output. Find the frequency at which the phase shift is zero and compare to the design frequency of 10kHz. Determine the ratio of the output to the input amplitude and compare to the value calculated in the prelab. V, R. ou in Figl
