Why certain counters like 74hc160 is called pre-set counters
How many bits a flip flop can save.
Purpose of stop bits and start bit
Which is the normal mode of operation of PROM (exactly yehi question statement tha confusing sa)

A circuit has 2 flip flops. What will be the power dissipation of the whole circuit is 5 volts and 5 mA current is applied to it. (I wrote 50mW. As for each flip flop its 25mW so 25+25 = 50..not sure)

QNO1:    Analyze the following timing dagiram and tell which counter is being depicted by the diagram.
QNO2:   give three guidelines for the selection of state assignment?
QNO3:  what does the statement given below (using PLD programming) mean? “YPIN23 ISTYPE.’com’”
QNO4: draw a diagram of a 3 bit-up-down counter. Use an external inputX; when X sets to logic 1, the counter downward otherwise countup wards.
QNO5: what is meant by state assignment?
QNO6: on the fifth  clock pluse a 4 bit jhonson sequence is Q0=0, Q1=1, Q2=1, Q3=1. What will be the sequence after sixth clock pluse.
Assume Q3 represent the least significant.
QNO7: what is the minimum sample frequency if the highest frequency component in analog signalis 20KHZ?
QNO8: what is meant by stop time and hold time of a flip flop?
