1. Figure 2 shows an operational amplifier. A voltage of 2 V is connected to the inverting input Vref as voltage offset. The circuit should have a 5 V power supply connected to the positive power rail (+Vcc) and the negative power rail (-VEE) to ground. Vref +Vcc -VEE Figure 2. Vo a) Compute Vo when Vi is supply with a DC voltage input, varying from -5V to +5V. Sketch the graph with Vi as the x-axis and Vo as the y-axis.

Which of the following statements accurately describe the sequence of operations of a DC to DC converter? O A. AC input voltage => AC to DC => DC to AC => change in voltage level => transmission to the Substation => AC to DC => DC voltage at a different level O B. DC input voltage => DC to AC => change in voltage level => transmission to the Substation =>AC to DC => DC voltage at a different level O C. DC input voltage => change in voltage level => DC to AC =>transmission to the Substation => DC voltage at a different level O D. None of the other choices are correct O E. DC input voltage => DC to AC => transmission to the Substation => AC to DC => DC voltage at a different level
