Answer #1

Given:

5-bit sequence number.

Sequence number starts with 0.

The total sequence from 5-bit sequence number = 25

                                                                             = 32 numbers

These numbers are ranged from 0 to 31

When sequence number starts with 0, the sequence number in Nth packet will be [(N mod 32)-1]

It is asked the sequence number after sending 70 packets. Therefore, we will use 71th packet.

For 71th packet, sequence number = [(71 mod 32)-1]

                                                        = 7-1

                                                        = 6

The 5-bit binary sequence for 71th packet is 00110

    Design a combinational circuit design that given a four-bit number as the input outputs an 8-bit number that represents the nth Fibonacci number in the sequence. For instance, if the input is 0001, the output should be the second number in the Fibonacci sequence. The Fibonacci series looks like the following: 0, 1, 1, 2, 3, 5, 8, 13, and so on. The first two numbers in the sequence are always 0 and 1. However, after that, you must add...
