A priority encoder is a combinational circuit that implements a priority function. The operation of the priority encoder is such that if two or more inputs are equal to 1 at the same time, the input having the highest priority takes precedence. The truth table for a four-input priority encoder is given below. With the use of X's, this condensed truth table with just five rows represents the same information as the usual 16-row truth table.

Make a k-map for each output segment (a, b, c, d, e, f, g) and write a Boolean function which describes each output as a function of inputs (and their complements). Fill in the resulting functions below. a:
Let G be a pseudorandom generator with length function l(n) = n + 1. Define a new function H by the rule H(rx) = r||G(x) , where |r| = 2. Thus H just passes the first 2 bits of its input through untouched and applies G to the last n – 2 bits. Prove with a full reduction that H is a PRG. (You can ignore the behavior of H on inputs of length less than 2.
Consider a logic function with inputs A, B, and C defi ned as follows: ■ If A or C is true, then output D is true, whatever the value of B. ■ If A or B is true, then output E is true, whatever the value of C. ■ Output F is true if exactly one of the inputs is true, although we don’t care about the value of F, whenever D and E are both true.

A Perceptron can learn the Majority function, i.e., where each input unit is a binary value (0 or 1) and it outputs 1 if there are more 1s in the input than 0s. Assume there are n input units where n is odd. Select one: True False
MATLAB code that matches the value from two variables within certain parameters. It can only use for or while loops, conditional statements, Boolean logic, or logical operators to find a match between the two inputs. For example, one input can be x = 42 and b = 61, and these two inputs would yield a match. The first condition that needs to be met to obtain a match is that x can be equal to 2, 21, 40, and 59. Variable b must also be equal to these values to have a match. The values for x have to increase by one for every loop iteration until the final values for x are: 19, 38, 57, and 76. So the matching has to take place within the same values for x as for b and within those range of values described. If a match is found then set b = d.
