3- Suppose that you have an optical isolator with the following characteristics: a- Forward current transfer ratio = 1. b- Input/output isolation is 1000V. c- Maximum input current = 25 mA d-LED forward voltage = 1.4V e- Maximum output transistor collector to base voltage = 50V f- Maximum output transistor current = 50 mA Suppose that you want to synthesize a logical NOR function in a circuit that is at 500 V above earth ground. The circuit has an isolated 25 VDC power source. Design the appropriate circuit for the input side and the output side.
