Overview of the Course

Here we will study what is noise and how it is classified.

Noise and its Types

Here we will study white noise, SNR and figure of merit.

White Noise, SNR and Figure of Merit

We will solve some questions and understand the related concept for solving these type of question of white noise.

Exercise on White Noise

Here we will study the effect of noise in AM, DSB & SSB.

Effect of White Noise on AM, DSB & SSB

Here we will study the mathematical analysis of noise and will derive few terms for coming derivation.

Noise in Analog Communication

Here we will derive the Figure of Merit for AM.

Figure of Merit of AM

Here we will derive the Figure of Merit for DSB-SC

Figure of Merit of DSB-SC

Here we will derive the Figure of Merit for SSB.

Figure of Merit of SSB

Here we will solve numerical on previous topics.

Exercise - 1

Here we will understand the Figure of Merit if FM receiver and will also solve one numerical.

Exercise - 2

Here we will solve few questions on Noise in FM topic.

Exercise on FM in presence of noise

Here we will study the basics of noise in digital communication.

Analog Communication for GATE

I am an Electronics engineer.Passionate to share my knowledge to students who actually need it.In my subject u definitely go well.

Vaibhav Goel

We will discuss all the theory plus questions important for GATE 2020 and ESE 2020. 
This will cover random process first followed by random variable.
Now I assure that this after watching this you have much confidence in this topic as before

(Hindi) Communication Random Variable and Random Processes Course : GATE (ECE)

Unless you dive into the depth of the most difficult problem, you can't turn impossible into possible. 

Himanshu Sen

This course deals with basic concepts related to probability and also it discusses about the random variable and random process and some important numericals.

Probability or Stochaistic Process

This course contains proper explanation of probability, random process and Random variable for the analysis of signal in communication which are unpredictable in nature.
