When the two input terminals of a NAND gate are short circuited, it acts as a NOT gate.
Below code can implement NAND gate in VHDL. The code is written in behavioral model. Library ieee; use ieee.std_logic_1164.all; Entity gates is port (a,b : in std_logic; c : out std_logic); end gates ; architecture and1 of gates is begin process(a,b) Begin If (a=1 and b=1) then C<='0'; Else C<= '1'; End if; End process; End and1;
It is a digital waveform.
If it is boolean logic, typically that is called a Truth Table.
complicated logic. intricate and involved logic.
math basically IS logic.

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
The two categories for logic gates are basic logic gates and universal gates. Gates are identified by their function and universal gates are identified as NAND gate or NOR gate.
A "Nand" gate is an "And" gate with an "Inverter" added to its output. To get a logic 1 output from a "Nand" gate, you need a logic 0 on both of its inputs. If I understand your question correctly, you have three "Nand" gates. Presumably the outputs of two of them are connected to the inputs of the third. Logic 1 at both inputs of the first two "Nand" gates will produce a logic 0 output from both of them. The two logic 0's are fed to the inputs of the third "Nand" gate producing a logic 0 output from the third "Nand" 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.
Any logic gate from which all other logic gate functions can be derived. The two universal gates are NAND and NOR.
Nand gate .
The NAND gate has two or more inputs, and one output. This output is the complement of the AND of all the bits and will only be 0 if all the inputs are 1.A NOT gate on the other hand has only 1 input, and the output is the complement of this input.So to make a NAND gate into a NOT gate, we should tie (short, connect to same value) all the inputs of the NAND gate. At the output we would have the complement of the signal given at the tied inputs.This way we have a NOT gate from a NAND gate.
That title of "Universal Gate" is reserved for NAND gates because you can build all possible logic using only NAND logic . You can build even other basic logic like AND, OR and NOT using NAND.
