i can pass diploma because of you sir. I can bet every ECE student knows your channel

[@EngineeringFunda]

EE too

[@jitenderjangra4388]

Sir explanation is best as i was studying the 6th edition of Kennedy’s electronic communication systems and unable to clear the doubt. Well done... sir

[@EngineeringFunda]

Thanks and welcome

[@Shuriken255]

Thank you very much! I see it's nothing complicated. It just saves difference from previous sample instead of saving sample itself and it allows smooth signals to have less bit depth.

[@UECAshutoshKumar]

Thank you sir ☺️

Thank you sir for these videos

[@EngineeringFunda]

Your positive comments motivates me, Thanks and welcome 🙏

[@richardhambel648]

I am confused when you say bandwidth because I though bandwidth means a range of frequencies?

[@EngineeringFunda]

Bandwidth can be also termed as data rate.

[@srushtikadam1514]

How is the number of levels decreasing in DPCM, only the range of max magnitude is decreasing right, NUMBER levels are still the same?

[@EngineeringFunda]

Here we reduce number of bits per sample

[@anuragsharma4159]

how do we know if the Signal is increasing or decreasing?You add 0.4V for 3.1 to 3.5 and 0.4 for 3.4 to 2.9 .

[@Er.rajinder]

same doubt

I am confused then how channel is different from bandawidth

[@prateekjaiswal1305]

In dpcm L is decreased so quantized error will increased

[@akhyarahmad672]

plz try to keep it less bookish but more logical and easy explanation..

👍

[@nitishsahani1382]

Very good but not the best

[@akankshagupta4625]

What is difference between pcm and dpcm

[@EngineeringFunda]

DPCM has different step size and PCM has unique step size.

[@rakeshreddy1365]

@@EngineeringFunda sir different step size is non uniform quantization right?
