BINARY NUMBER COMPARATOR Russian patent published in 2017 - IPC G06F7/02 G05B1/03 H03K5/22 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering and can be used for building automation equipment and functional units of control systems. The technical result is achieved by a binary number comparator, which is designed to generate features of relationships A>B, A=B, where A=a₁a₀, B=b₁b₀ are two-bit binary numbers determined by binary signals a₀, a₁, b₀, b₁ ∈ {0,1}, and comprise three XOR elements (1₁, 1₂, 1₃), four AND elements (2₁, 2₂, 2₃, 2₄) and four NOT elements (3₁, 3₂, 3₃, 3₄).

EFFECT: invention simplifies the device by reducing the number of types of logic elements used.
