In this assignment student will work in a group of two students to design digital logic circuits that fulfil the following requirements. The aim of the assignment is to design and implement the digital logic circuit that can show the decimal value of the binary numbers with the use of 7 segment display. The design is divided into 4 sections. The result of the earlier section will be used in the later section. Students will need to prepare report to explain how the design is implemented. The circuit diagram/block diagram and truth table need to be included. Each of the circuit must be simulated by the Logisim software in order to verify that it met the requirement. Use Logisim subcircuit to organize the circuit. The Boolean expression for each output signal must be provided. The logic circuit does not need to be simplified. Design Questions Requirement 1) Implement 3 to 8 decoder with logic gates. It should contain an enable signal (EN) with active high. When EN is low, all outputs are in low state. If EN is high, the decoder works normally. Implement 4 to 16 decoder by combining two 3 to 8 decoders Use the 4 to 16 decoders to implement a 4-bit binary numbers to binary coded decimal numbers (BCD) converter. Use 4 to 16 decoders to implement BCD to 7 segment display decoders. The complete circuit must be able to display the decimal value of the 4-bit binary numbers. 2) 3) 4 bits binary numbers XIX:XiXo System to display decimal value of 4-bit binary numbers.
