## Common Emitter Amplifier

The common emitter NPN amplifier circuit is shown in the figure below. The source VBB is applied to the input circuit in addition to the signal. The VBB battery provides the forward bias voltage to the emitter-base junction of the transistor. The magnitude of the forward bias voltage should be such that it should keep …

## Transistor as an Amplifier

The transistor raises the strength of a weak signal and hence acts an amplifier. The transistor amplifier circuit is shown in the figure below. The transistor has three terminals namely emitter, base and collector. The emitter and base of the transistor are connected in forward biased and the collector base region is in reverse bias. …

## Transistor

Definition: The transistor is a semiconductor device which transfers a weak signal from low resistance circuit to high resistance circuit. The words trans mean transfer property and istor mean resistance property offered to the junctions. In other words, it is a switching device which regulates and amplify the electrical signal likes voltage or current. The …

The addition and subtraction of the binary number system are similar to that of the decimal number system. The only difference is that the decimal number system consists the digit from 0-9 and their base is 10 whereas the binary number system consists only two digits (0 and 1) which make their operation easier. The …

The decimal number system has 10 digits from 0 – 9 and hence the base of the system is 10. On the other hand, the hexadecimal number system has 16 digits. The base of the hexadecimal number system is 16. The first 10 digits are expressed by the number and the remaining digits are represented …

The hexadecimal number are mostly used in microprocessor work. The base of the hexadecimal number is 16 and its consist the number from 0 -15. It uses the number system from 0-9 and then represents by the alphabets from A- F. The hexadecimal number system is also called hex. It is one of the convenient …

## Octal to Binary & Binary to Octal Conversion Methods

The base of the octal number system is 8 because it consists the digit from 0 – 7. The octal number system is converting into binary number system by grouping the binary digit in the group of three from the right of the binary number. On the other hand, the base of the binary digit …

## Binary to Decimal Conversion Methods

The decimal number system is represented by the digit 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. It consists ten digits and hence the base of the system is 10. Their base is increased by the factor of 10. On the other hand, the binary number system consists only two digits 1 and …

## Decimal to Binary Conversion Methods

The most popular way to convert a decimal number into the binary is the double dabble method. In this method, the given decimal number is progressively divided by 2 and writing the remainder after each division. When all the remainder is read in reverse order, the binary number is obtained. Steps for Decimal to Binary …

## Number System in Digital Electronics

Definition: In digital electronics, the number system is used for representing the information. The number system has different bases and the most common of them are the decimal, binary, octal, and hexadecimal. The base or radix of the number system is the total number of the digit used in the number system. Suppose if the …
