Let's Program the Transistors
In the campus placement season, it is better if we get company specific questions to prepare for the selection process. So, to help you out, we have already posted Question Banks for some core ECE companies and now, let us look at the following questions asked in recent times in Qualcomm interviews. In general, according…
Texas Instruments Question Bank continued from Part 1 Q. Draw 2:1 Mux using pass transistors. Ans: Two pass transistors are required to design 2:1 Mux. Q. Draw 2:1 Mux using transmission gates. Ans: Two transmission gates are required to design 2:1 Mux. Q. What is setup and hold time? Ans: Setup time is the minimum amount of time that an input signal…
Q. Implement a 3 bit asynchronous counter using T flip flops. Ans: To design 3 bit asynchronous counter we require 3 T flip flops. Q. What is the always block used for in Verilog? Ans: An always blocks runs continuously throughout the simulation. An always block can be made sensitive to one or more signals depending on the…
