Exercises: 1. Write the VHDL statements to describe a 4-bit comparator. Use the appropriate relational operators. Use input ports A and B, described above, as the inputs to the 4-bit comparator. Assume that three output ports, EQ, GT, and LT, have been declared in the Entity statement. Use them as the outputs from the comparator 2. Identify the package (or packages) that must be included in your VHDL code in order to use the relational operators with signals of type...

A comparator circuit has two 1-bit inputs A and B and three 1-bit outputs G (greater), E (equal), and L (less than). That is, G is 1 if A > B (0 otherwise), E is 1 if A == B (0 otherwise), and L is 1 if A < B (0 otherwise). a. Draw the truth table for a 1-bit comparator (the table has 2 inputs and 3 outputs). b. Implement G, E, and L circuits using only...

Following the circuit specification below: Comparator: A 3-bit comparator has six inputs A= A2A1A0 and B= B2B1B0, and one output: L. The comparator is a ‘less than’, meaning the output is ‘1’ is A<B. Using your method of choice, find the Boolean expression for the output of the comparator; Draw the logic circuit of the 3-bit comparator Available gates (no other gates can be used than the 5 listed below): 2-input NAND 2-input NOR 2-input AND 2-input OR Inverter

2 A comparator circuit has two 2-bit inputs, A(0,1) and B(0,1) [4 total inputs], and three 1-bit outputs, G (A greater than B), E (equal), and L (A less than B) (hint: Compare two bits against two bits, for example if inputs are 0010, then B is greater than A). Write the logic equation for each output, and draw the logic diagram for each output using 8 to 1 Multiplexers (3). Inputs Outputs F1 F2 F3 A1 AO B1 BOAB...

Part 1 Implement a 1-bit comparator as shown in the figure below using a 2x4 decoder. The comparator compares two bits A and B and produces three outputs Eq = 1 when A-B.G=1 when A > B, and L=1 when A<B. Your circuit must have the same inputs and outputs shown in the figure A B EN 1-bit Comparator Eq G L A = B A > B A<B
