Question

The input to the ideal operational amplifier shown in Figure 7-29 (p. 332)  is 0.5 V rms. Find the rms value of the output for each of the following combinations of resistor values: (a) R1 = Rf = 10 kOhm, (b) R1 = 20 kOhm, Rf = 100 kOhm

**Figure 7-29 (Exercise 7-6): Operational Amplifier Circuit** This figure illustrates an inverting operational amplifier circuit. The key components of the circuit include: - **Resistors:** - \( R_1 \): Connected to the input voltage \( v_i \). - \( R_f \): Feedback resistor connecting the output back to the input. - **Operational Amplifier:** - The op-amp has two input terminals: the inverting input (marked with a "-") and the non-inverting input (marked with a "+"). - The non-inverting input is grounded. - **Input and Output:** - \( v_i \): Input voltage entering through \( R_1 \) into the inverting input. - \( v_o \): Output voltage from the op-amp. The circuit functions as an amplifier where the output voltage \( v_o \) is an inverted, scaled version of the input voltage \( v_i \), determined by the ratio of the resistors \( R_f \) and \( R_1 \). This configuration allows the circuit to provide controlled gain to the input signal.
