Question: Non-inverting Summer A non-inverting summer interface device is shown in Figure P399. Of importance is that the input to the device has infinite resistance
Non-inverting Summer A non-inverting summer interface device is shown in Figure P3–99. Of importance is that the input to the device has infinite resistance – i.e. no current flows into the device. The output voltage for this configuration is two times whatever the input voltage is. Develop a relationship for the voltage vL across RL with respect to the two input voltages and the two input resistances.
