## Campanding

Non-uniform quantization can be achieved by passing the baseband signal through a compressor and then applying the compressed signal to a uniform quantizer. This video will help you to understand…

## Quantization

For the conversion of analog continuous signal to digital signal we should follow three processes Sampling ,Quantization ,Encoding. This video will help you to understand the concept of Quantization, use…

## Anti Alisiasing Filter

Anti Alisiasing Filter is used before the particular signal is sampled.On other hand we can say that to stop alisiasing from the signal we use Anti Alisiasing Filter. This video…

## Sampling Theorem

For the conversion of analog continuous signal to digital signal we should follow three processes Sampling ,Quantization and Encoding. This video will help you to proof the Sampling Theorem. Communication…

## Pulse Code Modulation PCM

Pulse digital modulation techniques are used to convert a continuous signal to digital signal. This video will help you to understand the concept of Pulse Code Modulation and basic elements…

## Pulse Position Modulation PPM

Pulse-position modulation (PPM) is a form of signal modulation.It is primarily useful for optical communications systems, where tends to be little or no multipath interference. This video will help you…

## Demodulation of PWM

If the duration of pulse or pulse width is changed as per the samples of message signal the resulting modulation is known as PWM (Pulse width modulation). This video will…

## Pulse Width Modulation PWM

PAM signals are affected by noise, this problem can be solved by using other pulse analog modulation schemes like PWM and PPM. This video will help you to understand the…

## Numericals on Noise Performance (Tutorial 11)

This video will help you to understand the numerical based problem on Noise Performance of DSB-SC, AM, FM. A receiver is an electronic device that receives radio waves and converts…
