Test Preparation

This lesson includes introduction to digital electronics. It describes types of number system and a brief description of each number system.

This lesson teaches how to convert a one number system to another number system.

Conversion of Base

This lesson contains few examples of conversion. After solving these examples you can perform any type of conversion.

Examples on Conversion

This lesson has covered the topic of operations on binary numbers. I have explained the arithmetic operations with example of each type.

Arithmetic Operations on Binary numbers

This lesson contains about the types of binary numbers. The representation of signed binary numbers. How we can write a negative and positive binary number.

Part 1 - Signed Binary Numbers

In this lesson I have explained the concept of r's complement. I have told how to calculate r's complement of a number by taking examples.

Part 2 - How to calculate r's complement

In this lesson I have taught, how to calculate the (r-1)'s complement by the help of few examples.

Part 3- How to calculate (r-1)'s complement

This lesson contains the short cut method to find the (r-1)'s complement of the number. It also contains some examples.

Questions on complements.

This lesson contains steps to perform subtraction operation using (r-1)'s complement. It contains few examples in it.

Binary subtraction using 1's complement.

Binary subtraction using 2's complement is taught in this lesson with few examples of it.

Binary subtraction using 2's complement

This lesson contains the binary codes and types of binary codes. The BCD code is discussed in this lesson which is a weighted binary code.

Binary Codes

In this lesson I have discussed about the gray code and excess 3 codes in details. The conversion of binary number to gray code and vice versa.

Non weighted binary code

This lessons contains the method to convert one binary code to another code. The weighted codes are being converted into the non weighted codes by following few steps.

Conversion of codes

Previous years Gate Questions on Number system with proper solutions are explained in this lesson.

Previous years questions

This lesson contains the basic logic gates which are used in digital circuits. Brief explanation of each gate is given in this lesson.

Introduction to logic gates

In this lesson I have explained the previous year question on NOT gate which was asked in GATE 2010 and IES 2010.

Previous year IES Question

Questions on propagation delay of NOT gate can be solved after learning this lesson. The total time period and frequency can be calculated.

NOT gate questions

In this lesson I have explained the two properties of AND gate. The working of AND gate with unused inputs in TTL and ECL logic.

AND gate properties

In this lesson I have explained the OR gates properties of enable/disable and the unused inputs.
The previous year gate question is explained in this lesson on AND OR gate.

OR gate properties

In this lesson I have explained the NAND and NOR gate properties of enable/disable and the unused inputs.

NAND NOR gate properties

In this lesson I have explained few important properties of ExOR gate and the enable/disable condition of this gate.

Ex-OR gate properties

In this lesson I have explained the important properties of Ex-NOR gate and the enable/disable condition.

Ex-NOR gate properties

In this lesson I have represented the basic gates i.e NOT,AND,OR in the NAND gate format. The NAND gate is proved as a universal gate.

NAND gate as universal gate- Part 1

In this lesson I have explained the XOR and XNOR gate as NAND gate representation. How many NAND gates are required to make these gates.

NAND gate as universal gate- Part 2

In this lesson I have explained the NOR gate as universal gate by making it as NOT, AND , OR gate.

NOR gate as universal gate- Part 1

In this lesson the NAND, XNOR and XOR gates are realised with the help of NOR gate.

NOR gate as universal gate- Part 2

The previous years Gate Questions on logic gates are explained in this lesson.
