Which two gates can be used to get output like NOT gate?

An Inverter or logic NOT gate can also be made using standard NAND and NOR gates by connecting together ALL their inputs to a common input signal for example. A very simple inverter can also be made using just a single stage transistor switching circuit as shown.

When all inputs of a NAND gate are connected together the resulting circuit?

NOT Gate: You may simply connect the two inputs in the NAND gate together to create a NOT Gate from the NAND Gate. Since the two inputs of the NAND gate are connected, only two input combinations can be used. The NAND Gate will emit a LOW if any input is HIGH. The NAND gate would be output HIGH if all inputs are LOW.

What does connecting together the inputs of NAND and NOR gates do?

Constructing the OR function Inverting the output of a NOR gate (with another NOR gate connected as an inverter) results in the OR function. The NAND gate, on the other hand, requires inversion of all inputs to mimic the OR function, just as we needed to invert all inputs of a NOR gate to obtain the AND function.

Which two logic gates can you combine in series to create an AND gate?

Explanation: NAND and NOR gates are called “Universal” gates as any kind of logic gate can be obtained by using combinations of these. To get an AND gate we can use two NAND gates.

How many and gates are required to implement the Boolean expression?

Boolean algebra Any Boolean function can be implemented using only AND and INVERT gates since the OR function can be generated by a combination of these two gates, as shown in Figure 2.20(a).

What gate can we make if we connect two inputs of NAND gate?

By De Morgan’s laws, a two-input NAND gate’s logic may be expressed as AB=A+B, making a NAND gate equivalent to inverters followed by an OR gate. The NAND gate is significant because any boolean function can be implemented by using a combination of NAND gates. This property is called functional completeness.

What happens if the two inputs of XNOR gate are connected together?

The two-input version implements logical equality, behaving according to the truth table to the right, and hence the gate is sometimes called an “equivalence gate”. A high output (1) results if both of the inputs to the gate are the same.

Why do we use NAND gates instead of and gates?

In general, cells are designed to have similar drive strength of pull up and pull down structures to have comparable rise and fall time. NAND gate has better ratio of output high drive and output low drive as compared to NOR gate. Hence NAND gate is preferred over NOR.

What happens if the two inputs of NOR gate are connected together?

The NOR gate is a digital logic gate that implements logical NOR – it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results. NOR is the result of the negation of the OR operator.

What is the purpose of combining simple logic gates?

Logic gates can be combined to form more complex inputs and outputs . These combinations are known as logic circuits . The three types of gate can be used in any combination to generate the desired output.

What logic gate is required for complementation?

NOT gate
The NOT gate (Inverter) performs the operation called as inversion or complementation. It changes one logic level to another logic level. A NOT gate is a logic circuit that has only one input and one output.
