[@shikheragrawal3830]

Thanks sir

[@PKMKB93000]

Sir I think compression will be till the line is linear and expansion will be the curved line

[@kratikabansal142]

Sir your videos are very informative. When will you upload other topics videos after companding ?

[@EngineeringFunda]

Soon my dear student. I am busy with my family so after few weeks you will get complete digital communication

[@kratikabansal142]

@@EngineeringFunda Thank you Sir :)

[@vimalajensi8261]

Sir waiting for more videos

[@bhanuprakashreddy]

can you use these in a- law to compress the image pixels

[@alankrit3]

why is the linear region expansion? it should be compression.

[@vamsi5052]

But where do will use expanding

[@EngineeringFunda]

Voice encoding

[@shreyashibhattacharya849]

Sir couldn't understand where the expansion is happening

[@koradasaikiran4146]

I too have the same query

[@soumyadeepbarik5711]

How mod y becomes mod x in the block diagram

[@umangverma3660]

Yeh raaz bhi usi k saath chala gaya

[@amitbarnwal4609]

Why it is called a law companding

[@umangverma3660]

Because there is a 'A'

[@jijofrancis5923]

Not satisfied in equation

[@veena05verma53]

in previous sheshan...😂
