16-5217 (Digital) Tutorial Sheet 1 Combinational Logic Design T. J. Mulroy 1. Design a circuit with a 2 bit binary input, which generates a binary output equal to the square of the binary input. Use gates and logic of your choice. 2. Sensors are used to monitor the pressure and temperature of a chemical solution stored in a vat. The circuitry for each sensor produces a HIGH voltage when a specific maximum is exceeded. An alarm requiring a LOW voltage input must be activated when either the temperature or pressure is excessive. What type of logic gate is required for this application? 3. Design a circuit that forms the binary sum of two 2-bit numbers as shown below. Design your circuit using basic combinational logic gates. A1 A0 B1 B0 + -------S1 S0 -------4. Explain the difference between two's complement, and two's complement number system....
