Define grammar of a language to write boolean expritions.

The language can recognize identifieres of boolean variables. It shoud recognize sympoles

of (&,|,~) respectivly (and/or/not).

Examples of valid expressions:

1- (~ x0 & ~ x1) | (x0' & ~ x1) )
2-  ~ (x0 & x1))
3- (x0 & y0) | (x1 & y1) | (x2 & y2)

Answer #1

SOLUTION-

let set of terminals (booleam variables in this case eg x0,x1 etc)

Idea is to generate grammer which creates <and>, <or> between two non terminals and <not> a non terminal.

The grammer is:

in case of more terminals, just append them in the production rule.

Design a combinational logic circuit that accepts a decimal value represented as a four-bit Aiken (or "2421") code (X3 X2 X1 X0) as its input and that creates a four-bit output (Y3 Y2 Y1 Y0) that uses standard binary (radix-2) encoding to represent the same decimal value.

Write a BNF grammar for a new language called 4040. It should include the following rules: Variable definitions should start with var. There must be only single space after var. Variable names should come after the var and single space. Variable names should start with a letter or underscore(_). Starting with a digit is not allowed. Variable names can have digits after the first letter. There can be multiple variable names separated by comma. Between variables, spaces are allowed. There...

Define a Q-sequence recursively as follows. B.   x, 4 − x is a Q-sequence for any real number x. R.   If x1, x2,   , xj and y1, y2,   , yk are Q-sequences, so is     x1 − 1, x2,   , xj, y1, y2,   , yk − 3. Use structural induction (i.e., induction on the recursive definition) to prove that the sum of the numbers in any Q-sequence is 4. Base Case: Any Q-sequence formed by the base case of the definition has sum x +...
