Part A Answer all the questions Marks : 20 x 1 = 20 Fill in the blanks (Q1 -.- Q6): _waveforms consists of logic levels that are changing back 1 and forth between the HIGH and LOW levels or states. N If A and B are the inputs to a two-input gate, then the output Y is HIGH only if the inputs are at same logic levels. A+ = (A + B) (A + C) 3 4 In digital sequential circuit, the present not only depends on the present input but also on the previous output of the circuit. is used for temporary storage of data/program instructions in microprocessor based systems. 5 6 IC 7400 is a _gate. Choose the correct answer (Q7 -- Q13): 7 (A + B) is equal to a) A+B b) A+B c).B d) A.B
