Course work on discipline: "Electronics and microprocessor technology"
R&D: “Development of an adder of binary eight-digit numbers taking into account the sign”

Year: 2010

Assignment: It is required to develop a device, the inputs of which are supplied in parallel code with two eight-bit binary numbers A and B, and the output of which requires the sum of these two numbers - C, taking into account the sign.

The device under development should perform the summation of two binary numbers, taking into account the sign, displaying the result on a digital indicator. The device should be implemented on digital integrated circuits (IC) TTL.
