Figure 1   RC Circuit

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

Lab 7     AC circuits

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


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?
