Rather than use transistors your friend W. Too wants to use diodes to implement logic gates. He shows you the circuit he designed shown in figure 5. If A and B can swing all the way from 0 V to VDD, does the circuit implement a logic gate? If so what gate is it and what is its static discipline? Assume the diode is modeled by an ideal diode with a series resistance RD V. DD R₁ L ΟΥ AO Bo Figure 5: Diode Based Logic Gate

You are an electrician working on an overhead crane. The crane uses a large electromagnet to pick up large metal pipes. The magnet must have a minimum of 200 VDC to operate properly. The crane has an AC source of 240 V. You are given four diodes that have a peak voltage rating of 400 V each. These diodes are to be used to form a bridge rectifier to convert the AC voltage into DC voltage. Is the voltage rating of the diodes sufficient? To the nearest volt, what will be the DC output voltage of the bridge rectifier?
