English Alphabet (A..Z) are represented numerically by (0..25), e.g. A is 0, B is 1, etc. Use Caesar’s Cipher to encrypt the message HELLO WORLD with the Key being 4.

Expert Solution

Char = H
   H is 7
   7 + 4 = 11
   11 mod 26 = 11
   11 => L
Char = E
   E is 4
   4 + 4 = 8
   8 mod 26 = 8
   8 => I
Char = L
   L is 11
   11 + 4 = 15
   15 mod 26 = 15
   15 => P
Char = L
   L is 11
   11 + 4 = 15
   15 mod 26 = 15
   15 => P
Char = O
   O is 14
   14 + 4 = 18
   18 mod 26 = 18
   18 => S
Char = W
   W is 22
   22 + 4 = 26
   26 mod 26 = 0
   0 => A
Char = O
   O is 14
   14 + 4 = 18
   18 mod 26 = 18
   18 => S
Char = R
   R is 17
   17 + 4 = 21
   21 mod 26 = 21
   21 => V
Char = L
   L is 11
   11 + 4 = 15
   15 mod 26 = 15
   15 => P
Char = D
   D is 3
   3 + 4 = 7

2. i. Consider a binary source alphabet where a symbol 0 is represented by 0 volt and a symbol 1 is represented by 1 volt. Assume these symbols are transmitted over a baseband channel having uniformly distributed noise with a probability density function: px= {18 for-4≤x≤4 0 Assume that the single decision threshold T is in the range of 0 and l volt. If the symbols 0 and 1 are sent with probabilities p0 and 1- p0 respectively, derive...

Theory of computation: Consider the alphanumeric alphabet Σ = {a, b, . . . , z, A, B, . . . , Z, 0, 1, . . . , 9} and let L be the language of all regular expressions over Σ: L = {w ∈ Σ ∪ {∅,(,), ∪, ·, * }* | w is a syntactically legal regular expression over Σ} Give an unambiguous context-free grammar that generates L. The grammar should use the following precedence levels, from...
