Assume that there are a device, DUT, and a provided test scenario as shown in Figure 1. The only thing known about DUT is that it is a frequency dependent circuit. That means when there is a change in input frequency, the output's gain or phase are prone to change. Your supervisor assigned you to analyze and present such behavior of DUT. You immediately supplied the circuit with a waveform generator as vin (t), and connected an oscilloscope to vout (t). Each equipment and DUT do not fail under any condition and are working in order. Questions: 1. Explain how to measure the change in output gain and phase. 2. Explain how to find the expected design frequency range of DUT. 3. Explain when the intended voltage gain of the DUT design occurs. Why? 4. What might be the expression for vout (t) when vin (t) = 2 cos(2700t) [V]? Describe the notions you used in your expression clearly. + EE313 Electronic Circuits II Preliminary Assignment 1 Vin(t) - DUT Figure 1: Device under test + Vout (t)
