Write a python function c that converts bitstring array back to an integer numpy array

tresset_1 [31]

Answer:

import numpy as np#importing numpy module with an alias np.

def c(bitstring_array):# defining function c.

num_integer=bitstring_array.dot(2**np.arange(bitstring_array.size)[::-1])#bitstring conversion.

return num_integer#returning integer array.

print("Enter bits")

Bit_l=input().split(" ")#enter space separated bitstring.

for i in range(len(Bit_l)):#iterating over the bitstring.

Bit_l[i]=int(Bit_l[i])

bitstring_array=np.array(Bit_l)

print(c(bitstring_array))#function call.

Output:

Enter bits

Write the logical Expression and Draw the Truth table for the <br> following questions

Alja [10]

The logical expressions are

(X NOR Y ) OR Z ⇒ $(\bar X \bar + \bar Y) + Z$
(A NAND B) AND NOT C ⇒ $(\bar A \bar \cdot\bar B) \cdot \bar C$

<h3>How to determine the logical expressions?</h3>

<u>Logical expression 1</u>

X and Y are linked by the NOR gate.

So, we have:

X NOR Y

The X NOR Y is linked to Z by the OR gate.

So, we have:

(X NOR Y) OR Z

Hence, the logical expression is (X NOR Y ) OR Z ⇒ $(\bar X \bar + \bar Y) + Z$

<u>Logical expression 2</u>

A and B are linked by the NAND gate.

So, we have:

A NAND B

The A NAND B is linked to C by the AND gate.

So, we have:

(A NAND B) AND C

Hence, the logical expression is (A NAND B) AND NOT C ⇒ $(\bar A \bar \cdot\bar B) \cdot \bar C$
