Logic gate is mainly implemented electronically using diodes or transistors, but can also be built using the arrangement of components that utilize the properties of electromagnetic relay , fluids, optical or even mechanical. Any Boolean algebra operation can be associated with inputs and outputs represent the statements of Boolean algebra.

Although these circuits may be complex, they may all be constructed from three basic devices. We have three different types of logic gates. The OR gate has two or more inputs and one output. The Boolean expression: The AND gate has two or more inputs and one output. In Boolean algebra, multiplication sign either x or. The NOT is a one input and one output. An OR gate can be realize by the electronic circuit, making use of two diodes D 1 and D2 as shown in the figure. Here the negative terminal of the battery is grounded and corresponds to the 0 level, and the positive terminal of the battery i.

The output Y is voltage at C w. The following interference can be easily drawn from the working of electrical circuit is: Truth Table: Theory and Construction: An AND gate can be realize by the electronic circuit, making use of two diodes D 1 and D2 as shown in the figure. The resistance R is connected to the positive terminal of a 5V battery permanently.

The following conclusions can be easily drawn from the working of electrical circuit: PAGE No. A NOT gate cannot be realized by using diodes.

However an electronic circuit of NOT gate can be realized by making use of n-p-n transistor as shown in the figure. The base B of the transistor is connected to the input A through a resistance Rb and the emitter E is earthed. The collector is connected to 5V battery. The following conclusion can be easily drawn from the working of the electrical circuit: Two ideal p-n junction diode D1 and D2 , a resistance R, an ideal n-p-n transistor. The output Y is voltage C w. It means if A and B are not identical i.

It is a sample of class 12th C.

After the next Km will reset the first digit to 0 and carry 1 to the next digit, making the figure of the odometer as Similarly the third Km will make the figure and the next Now as we have done in the decimal system, we can assign the weight or the place value for the binary system.

This system has a base of two so every digit in this system can be represented by 2 raised to some power and multiplied to that digit.

As we have seen that after travelling four Kms the binary odometer gives you We can check this as Abbildung in dieser Leseprobe nicht enthalten So in this system the digit on extreme right side is the least significant and is termed as LSB least significant bit and the extreme left digit is the most significant and is termed as MSB most significant digit.

## Logic gate

Binary to decimal conversion Binary number can be converted into the decimal numbers very easily by using the concept of the weight of the digit or the place value of the digit. The following procedure is used for this conversion I.

Write the binary number II. Directly under the binary number write Abbildung in dieser Leseprobe nicht enthalten working from right to left. If a zero appears in a digit position cross out the decimal weight for that position. Obtain the remaining weight to obtain the decimal equivalent.

As an example, let us try to convert to its decimal equivalent, now Abbildung in dieser Leseprobe nicht enthalten Take an another example to understand this, let us Abbildung in dieser Leseprobe nicht enthalten We can also convert the binary fractions into decimal. Let us suppose we want to convert 0. So the conversion of 0.

Decimal to binary conversion Decimal numbers can be converted into the binary numbers very easily by reversing the process described in the previous article. The method to convert decimal to binary is called as Double Dabble.

In this method we have to divide the decimal number by 2, writing down the remainder after each division.

Then to obtain binary number the remainder is taken in the reverse order. We have to continue the process of dividing by 2, till we get a quotient of 0 and the remainder of 1.

Let us take an example, Convert decimal 11 to its binary number. Abbildung in dieser Leseprobe nicht enthalten Write down all the remainders in these steps in reverse order, we get The arrow shows the direction of the order of the remainders to get binary numbers So the binary number is We can also convert a decimal fraction to the binary number by multiplying the fractional number by 2 and record a carry in the integer position. The carries read downward are the binary fractions. As an example let us convert 0. Abbildung in dieser Leseprobe nicht enthalten And so on. Solid-state storage SSS is a type of computer storage media made from silicon microchips.

Because if i was to call an and gate an and gate or an or gate an or gate it would look confusing. Thanks, Mansoor Alam. Thanks, man. I am in Middle school and my dad is teaching CS50, a Harvard coding class at a high school, I saw him go over different gates so I build each one in the game Minecraft using Redstone, basically wires.Walther Bothe , inventor of the coincidence circuit , got part of the Nobel Prize in physics, for the first modern electronic AND gate in The magnitude of the energy barrier can be tuned by adjusting the compression distance h, which is an additional design parameter apart from geometric dimensions.

Both the bubble and the wedge can be used on distinctive-shape and rectangular -shape symbols on circuit diagrams, depending on the logic convention used. Figure 1 shows the sinusoidaly varying current as an analog signal.

Nevertheless, it is important that a designer understand the underlying mathematical description and solution of the problem.
