Procedure 1. To measure the unity-gain frequency of the operational amplifier, connect the following circuit: 2. Using a dual-trace oscilloscope, observe Vs and Vo. Increase the frequency of the signal generator, and record the frequency where Vo decrease to 0.707 time its value at 100Hz. 3. To demonstrate that the gain-bandwidth product is constant, connect the following circuit: 4. With Rf = 47Kohm,measure the output voltage Vo. Increase the frequency of the signal generator until the output voltage decrease to 0.707 times its value at 100Hz.Record the
