a Problem 7 A cathedral wants to add special lights to the Cross on its tower for the Easter. The cross includes 8 bulbs; a string of four blue horizontal bulbs, and a string of four orange vertical bulbs. Each bulb needs 5-Volts to fully light. One of the cathedral's nuns designed an electronicircult to make the Cross light in a special manner. All diodes in the design can be assumed Ideal (zero threshold voltage). The two buffer ICs have a threshold voltage of 3V (Ignore hysteresis). The transformer powering this circuit is center-tapped and has a total RMS output of around 7V. The frequency of the source is 50Hz. Assuming all components have no internal delay, describe exactly and in detail how the Cross will light. (Hint: To make sure you don't lose the full mark of the problem if you do a mistake, plot a separate graph of the voltages at each of the labeled points. Start from the left and move towards the right. This will help you know how the Cross will light). we 240:7 (В) J45V +5V Zike TL 2404 502 Leslie T 1ΚΟ Bull D
