Question
**Problem Statement:** 3. In the circuit below, assume the op amp is ideal. - **a.** Find the transfer function Vo/Vin (leave Rf, Rs, and C as variables). - **b.** What type of filter is it? If Rf = 10kΩ, Rs = 1kΩ, C = 2μF: - **c.** Find the passband gain. - **d.** Find the corner frequency. - **e.** Sketch the Bode plot for the magnitude of the transfer function. **Diagram Explanation:** The circuit is a non-inverting op-amp configuration with a feedback network consisting of a resistor (Rf) and a capacitor (C) in parallel. An input resistor (Rs) is connected to the inverting input, and the non-inverting input is grounded. The output voltage (Vo) is taken from the op-amp output. **Important Components:** - **Op-Amp:** Ideal operational amplifier, providing infinite gain, infinite input impedance, and zero output impedance. - **Resistors (Rf, Rs):** Rf is the feedback resistor, and Rs is the series resistor connected to the input voltage (Vin). - **Capacitor (C):** In parallel with Rf, forming a frequency-dependent network. This setup is used to analyze the filter's characteristics, including its type, gain, and frequency response.
