By using 5 NOR gates, we can implements half-subtractor.
The inputs for 1st NOR gate are A and B,
for 2nd NOR gate inputs are the output of 1st NOR gate and A input,
for 3rd NOR gate inputs are the output of 1st NOR gate and B input,
for 4th NOR gate the inputs are gates 2 and 3, and for last gate input is the output of the 4th gate.

∙ 9y agoMaking a full subtractor using nand gates is very similar to making a half subtractor using nand gates. All you would do is construct the adding a whole adder.

What is the flip flop draw the circuit diagrem of all flip flop and explain the working of flip flop using nor gates?
draw a logic circuit of the clocked SR flip-flop using NOR gate
How many gates you can make using universal gates?
Seven gates, they are: not, and, or, nor, nand, xor, xnor.
Define universal gate?
A logic circuit of any complexity can be realized by using only the three basic gates (NOT, AND, and OR Gates). There are two universal gates, the NAND Gate and the NOR gate. Each of those can also realize logic circuit single-handedly. The NAND and NOR gates are therefore called universal gates.
Design full adder using only nor gates?
12 NOR gates are required to implement full adder
Device a circuit to perform OR logic using only NOR gate?
Use two NOR gates. Tie the output of the first to both (or all) inputs of the second. A logic one at any input of the first produces a logic one at the output of the second which is a standard OR.
What is the definition of universal gate?
universal gates are the ones from which we can design other gates also. for eg. NAND and NOR gates. they help in forming the uniformity in the circuits.
Draw logic diagram of two to four line decoder using nor gates only with enable input?
draw logical diagram 2 to 4 line decoder with nor gates only
Can an AND gate be formed by using two OR gates?
AND gate is A.B If two not gates are added at both inputs of and gate then output becomes A'.B' which is equal to (A+B)' by DeMorgan's law. hence the nor gate is formed Update: Put more simply, invert A and B by attaching A to both inputs of one NOR and attaching B to both inputs of another NOR, then NOR the results of the previous two NOR gates. Total of three NOR gates in a two-level implementation. NAND can obviously be created by inverting the result.
What is universal logic gate?
universal logic gate is a gate using which you can make all the logic gates there are two such gates NOR gate and NAND gate
What are basic gates. Why they are called so?
Nand and nor gates are called universal gates .they called so as since any logic function can be done with nand and nor gates
Digital electronics logics gate?
and gates or gates nor gates nand gates are the electronics logic gates.
