Figure 1   RC Circuit Table 1 contains voltage readings for the circuit in Figure 1. The gain Vo/V is expressed in dB.

The input and output voltages for the circuit shown in Figure 1 were measured and the gain, V_o/V was calculated in dB. Recall that,

(1)

Plot the gain in dB as a function frequency on the attached semilog paper. Use the logarithmic axis for the frequency.

Q. What is the value of the RC time constant?
