5.37 Determine the output of the summing amplifier in Fig 5.74

### Section 5.6: Summing Amplifier

#### Problem 5.37
Determine the output of the summing amplifier shown in Figure 5.74.

**Figure 5.74:**
- The diagram features an operational amplifier configured as a summing amplifier.
- There are three input voltages: 
  - 3V connected through a 10 kΩ resistor,
  - 5.4V connected through a 20 kΩ resistor,
  - -3.5V connected through a 30 kΩ resistor.
- These inputs are connected to the inverting terminal (-) of the op-amp.
- The non-inverting terminal (+) is grounded.
- The feedback path includes a 30 kΩ resistor connected from the output to the inverting terminal.
- The output voltage is denoted as \( v_o \).

#### Problem 5.38
Using Figure 5.75, design a problem to help other students better understand summing amplifiers.

**Additional Notes:** 
- Figure 5.75 is mentioned but not displayed in the image. It is suggested for creating educational material or exercises related to summing amplifiers.
- This exercise encourages an understanding of how different input voltages and resistors affect the output of a summing amplifier circuit.
