Question 1- Obtain the minimal NAND and NOR logic functions required to drive the bottom horizontal bar of a seven-segment display, as shown above.
Question 2- Design a minimized first canonical form logic circuit which takes a BCD input and converts it to an Excess 3 code
Question 3- The input to a logic circuit is a 3 bit binary number. The output is the square of the input. Implement the design using a 3x6x4 PLA.
Question 4- Design a synchronous Modulo 8 counter using JK Flip - Flops.
Question 5- For the feedback register shown in Figure 1, determine the count sequence. Assume an initial state of Qa, Qb, Qc, Qd,Qe = 10000.
Question 6- Design a sequential logic system, using JK Flip-Flops, which detects a bit pattern of 1101 in a stream of serial data.
What do the letters PCM and PAM stand for? Why is PCM transmission preferred over PAM transmission? Give at least two reasons in your answer.
A 20-m3 tank contains nitrogen at 23 C and 600 kPa. Some nitrogen is allowed to escape until the pressure drops to 400 kPa and the temperature to 20 C. Determine the amount of nitrogen gas that has escaped in kg. How much in this in Kmoles
