What can be used to implement a logic function?
Logic gates implementation or logic representation of Boolean functions is very simple and easy form. The implementation of Boolean functions by using logic gates involves connecting output of one logic gate to the input of another gate. Commonly used Logic Gates are: AND, OR, NAND and NOR gates.
Is it possible to create any digital logic circuit just using and or not gates?
Individual logic gates can be connected together to form a variety of different switching functions and combinational logic circuits. In fact, it is possible to produce every other Boolean function using just the set of AND and NOT gates since the OR function can be created using just these two gates.
Which logic operation gate can be used to create any digital circuit on its own?
In the field of digital electronic circuits, this implies that it is possible to implement any Boolean function using just NAND gates.
What is the difference between combinational and sequential circuits?
Combinational Circuit is the type of circuit in which output is independent of time and only relies on the input present at that particular instant. On other hand Sequential circuit is the type of circuit where output not only relies on the current input but also depends on the previous output.
How do you create a logic gate?
Simple digital logic gates can be made by combining transistors, diodes and resistors with a simple example of a Diode-Resistor Logic (DRL) AND gate and a Diode-Transistor Logic (DTL) NAND gate given below.
How to make simple logic gates and circuits?
Simple Logic Gates and Circuits. 1 Step 1: AND Gates. The first type of gate we will look at is the AND gate. The circuit symbol for a two-input AND gate is that funny bullet-shaped 2 Step 2: OR Gate. 3 Step 3: NOT Gates and Combinations. 4 Step 4: Logic Circuit Synthesis. 5 Step 5: Final Example.
What is the input voltage of logic gates?
Logic gates have one or more input terminals, and the voltage at these terminals are translated into Boolean inputs of 1 or 0. Typically a high voltage is read as a 1 and a low voltage as a 0.
How do diode logic gates work?
Diode logic gates use diodes to perform OR and AND logic functions as shown in the circuit diagram. Connection of the LED at the output is optional which simply displays the logical state of the output, i.e. the logic state of output is 0 or 1, if LED is off or on, respectively.
What is the output of the NOR gate on the left?
The NOR gate on the left has an output of 1 because both its inputs are 0 initially. If you close the gate on top, the output of the NOR gate on the right becomes 1 because both its inputs are now 0 and the bulb lights up. Here’s the crazy bit (no pun intended): if you now open the gate on top, the bulb still remains lit!
