How many gates are in a digital circuit?
There are seven basic logic gates: AND, OR, XOR, NOT, NAND, NOR, and XNOR. The AND gate is so named because, if 0 is called “false” and 1 is called “true,” the gate acts in the same way as the logical “and” operator. The following illustration and table show the circuit symbol and logic combinations for an AND gate.
What is the minimum number of gates that you need to implement the circuit shown above draw the circuit?
1 0
Here, the output Z is a logic 1 when either but not both inputs A and B are logic 1. The truth table for the EX-NOR gate is shown in Table 5.18. Here, the output Z is a logic 0 when either but not both inputs A and B are logic 1. This is the logical inverse of the EX-OR gate….5.3. 5 Truth Tables.
| A | B | Z |
|---|---|---|
| 1 | 0 | 0 |
| 1 | 1 | 1 |
What is the minimum number of NAND gates required?
0
Detailed Solution. Therefore simply take A as output and ignore all other inputs and hence the minimum number of NAND gates required is 0.
How many NOR gates are required to form NAND gate?
Constructing the NAND function For a two-input gate, this requires three more NOR gates connected as inverters.
How many AND gates are required to realize the following expression y CD EF G?
two AND gates
Explanation: To realize Y = CD + EF + G, two AND gates are required and two OR gates are required.
What is the minimum number of NAND gates required to release and XNOR gate?
5 NAND gates are required to realize an XNOR gate. 5 NAND gates are required to realize an XNOR gate.
How many NOR gates are required to form NAND gates?
Constructing the NAND function To make a NOR gate perform the NAND function, we must invert all inputs to the NOR gate as well as the NOR gate’s output. For a two-input gate, this requires three more NOR gates connected as inverters.
How many not gates are required for the construction of a 4-to-1 multiplexer?
two NOT gates
How many NOT gates are required for the construction of a 4-to-1 multiplexer? Explanation: There are two NOT gates required for the construction of 4-to-1 multiplexer. x0, x1, x2 and x3 are the inputs and C1 and C0 are the select lines and M is the output.
What are the logic gates in a digital circuit?
Digital Circuits – Logic Gates. Digital electronic circuits operate with voltages of two logic levelsnamely Logic Low and Logic High. The range of voltages corresponding to Logic Low is represented with ‘0’. Similarly, the range of voltages corresponding to Logic High is represented with ‘1’.
What is the minimum number of NOR gates required to implement FS?
Minimum number of NOR Gate required implementing FS = 9 4. FS can be implemented by a combination of one 3×8 decoder and two OR gate.
What is the range of voltages in digital circuits?
Digital electronic circuits operate with voltages of two logic levels namely Logic Low and Logic High. The range of voltages corresponding to Logic Low is represented with ‘0’.
Why are the three universal logic gates considered minimal sets?
So by using these three Universal Logic Gates we can create a range of other Boolean functions and gates. However, the NAND and NOR gates are classed as minimal sets because they have the property of being a complete set in themselves since they can be used individually or together to construct many other logic circuits.
