0,1,2,3,4,5,5,6
9. Design a counter in such a way that 0,3,1,2,2,1,3,0
10.Count no. of 1’s in 8 bits using only combinational circuit
11. Design a 1- bit comparator using 4:1 MUX
12. Design a 4- bit comparator using 4:1 MUX
13. Draw the waveforms of Qa and Qb
20 --> 23 --> 41 --> 30 --> then again 20 and so on cycle continues
It means it has to count 20 clock cycles first then make to 0 and then count 23 cycles and should make to 0… so on….
15.How can u find the largest number out of 100 elements? Write a C Code ?
16. Simplify : AC’+AB’+BC’
17. How many 2:1 Mux are used to implement inverter? So that how many 2:1 Mux are used to implement XOR?
18.What is set up time and hold time? Does the D-latch have Set-up time
19. Draw D-latch using MUX
20. What is clock-gating? What is effect of clock-gating
21. Convert D-FF to T-FF
22. Draw PD flow, ASIC flow
23. Write the boolean equation for:
24. Draw the inverter characteristics
25.In ASCII Number, 3A is subtracted from 4A? What is the range of Address locations? How many bits are used to store this range?
26. Draw the Circuit for this waveform?
27.Write a verilog code to calculate the frequency of the below waveform?
28.Draw the Circuit for this waveform?
