A full binary subtractor has _______ input lines and _______ output li...
A full subtractor is a combinational circuit that performs subtraction of two bits, one is minuend and other is subtrahend, taking into account borrow of the previous adjacent lower minuend bit. This circuit has three inputs and two outputs. The three inputs are minuend, subtrahend, and previous borrow. The two outputs represent the difference and output borrow.

A full binary subtractor has _______ input lines and _______ output li...
A full binary subtractor is a combinational circuit that performs the subtraction of two binary numbers. It takes three inputs - the minuend (the number from which the other number is subtracted), the subtrahend (the number subtracted from the minuend), and the borrow-in (the borrow from the previous lower significant bit).
The inputs of a full binary subtractor are as follows:
1. Minuend input (A): This is the higher significant bit of the minuend.
2. Subtrahend input (B): This is the higher significant bit of the subtrahend.
3. Borrow-in input (Bin): This is the borrow from the previous lower significant bit.
The outputs of a full binary subtractor are as follows:
1. Difference output (D): This is the difference of the minuend and subtrahend.
2. Borrow-out output (Bout): This is the borrow generated from the current bit position.
Explanation of the options:
a) Option A (2 input lines and 2 output lines): This is incorrect because a full binary subtractor requires 3 input lines (A, B, and Bin) and 2 output lines (D and Bout).
b) Option B (3 input lines and 3 output lines): This is incorrect because a full binary subtractor requires 3 input lines (A, B, and Bin) and 2 output lines (D and Bout).
c) Option C (2 input lines and 1 output line): This is incorrect because a full binary subtractor requires 3 input lines (A, B, and Bin) and 2 output lines (D and Bout).
d) Option D (4 input lines and 2 output lines): This is incorrect because a full binary subtractor requires 3 input lines (A, B, and Bin) and 2 output lines (D and Bout).
e) Option E (3 input lines and 2 output lines): This is the correct answer because a full binary subtractor requires 3 input lines (A, B, and Bin) and 2 output lines (D and Bout).
Therefore, the correct answer is option E (3, 2).
The inputs of a full binary subtractor are as follows:
1. Minuend input (A): This is the higher significant bit of the minuend.
2. Subtrahend input (B): This is the higher significant bit of the subtrahend.
3. Borrow-in input (Bin): This is the borrow from the previous lower significant bit.
The outputs of a full binary subtractor are as follows:
1. Difference output (D): This is the difference of the minuend and subtrahend.
2. Borrow-out output (Bout): This is the borrow generated from the current bit position.
Explanation of the options:
a) Option A (2 input lines and 2 output lines): This is incorrect because a full binary subtractor requires 3 input lines (A, B, and Bin) and 2 output lines (D and Bout).
b) Option B (3 input lines and 3 output lines): This is incorrect because a full binary subtractor requires 3 input lines (A, B, and Bin) and 2 output lines (D and Bout).
c) Option C (2 input lines and 1 output line): This is incorrect because a full binary subtractor requires 3 input lines (A, B, and Bin) and 2 output lines (D and Bout).
d) Option D (4 input lines and 2 output lines): This is incorrect because a full binary subtractor requires 3 input lines (A, B, and Bin) and 2 output lines (D and Bout).
e) Option E (3 input lines and 2 output lines): This is the correct answer because a full binary subtractor requires 3 input lines (A, B, and Bin) and 2 output lines (D and Bout).
Therefore, the correct answer is option E (3, 2).
