4 Bit Subtractor Ic. A 4 bit parallel subtractor is used to subtract a number consisting of 4 bits. The most basic arithmetic operation is the addition of two binary digits.
This simple addition consists of four possible elementary operations. What is the logic diagram of 4 bit subtractor. The most basic arithmetic operation is the addition of two binary digits.
0 0 0 0 1 1 1 0 1 and 1 1 10.
We get a 4 bit parallel subtractor by cascading a series of full subtractors. 0 0 0 0 1 1 1 0 1 and 1 1 10. The most basic arithmetic operation is the addition of two binary digits. For an n bit parallel subtractor we cascade n full subtractors to achieve the desired output.
