Extracted text: 3. What is an operational amplifier?, explain in your own words 4. What is an inverting amplifier?, How could you calculate the gain?, draw an example and explain. 5. What is a non-inverting amplifier? How could you calculate the gain?, draw an example and explain. 6. What is an summing amplifier?, How could you calculate the gain?, draw an example and explain. 7. Design an inverting amplifier with a gain of 2. Use +5 V and -5V power supplies and an ideal op amp. Simulate your design in Multisim. Use a sinusoidal form as an input. (See Fig 1).F =1Khz 8. Design a non-inverting amplifier with a gain of 4. Use +5 V and -5V power supplies and an ideal op amp. Simulate your design in Multisim. Use a sinusoidal form as an input. (See Fig 2).

Design a summing amplifier with two sine inputs and a gain of 2. Use +10 V and -10V power supplies and an ideal op amp. Simulate your design in Multisim. 10. Could you build an amplifier (inverting, non-inverting and summing) using one power supply? Explain. 11. Design a single power supply inverting amplifier with a gain of 2 gain (See Fig 3). Use 1Khz sine wave for Vin, Vcc=5V, RA =RB = 10KN. Calculate Vo , C1, C2, R1, Vin and R2. Simulate your design in Multisim. wwip
