Convert each of the following equations directly to gate-level circuits using any of the standard gates discussed in class (NOT, AND, OR). You may use gates with more than two inputs if needed. a. F(a, b,c) = ab + bc + c b. F(a, b, c,d) = ab + bod c. F(a, b,c, d) = (a + b) * (c+d) +c+d

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
