Oh and the comminication part.The analogue to digital thing.How to make it better.What is a digital signal.And how to represent 1100 in analogue form.
Btw lol what was the ans for 1100 thingy?:p Idk why they wrote 2.5mV for some reason for the lsb?:p

I got 30
Cause i thought that lsb shows 2.5 right so that mean 1 corresponds to 2.5mV
so then 1100 ie 12 = 12*2.5 = 30mV

Actually I have never seen any defition of digital signal signal only.:p I just wrote it is data represented in binary form (ie 1 and 0) and it has a base of 2.:p

Yep 1 would be msb
and ikrr! i had no idea what else to write for another mark :p
So I was wondering if lsb is 2.5 then for 1100 0 is lsb then what to multiply 12 by since msb is not given?:p Ik it kinda doesn't matter anymore but xP jlt for knowledge sake.:p

Also, what do you guys think you would rate as the paper toughness, lol cause this time it is just Indians so then we can make a guesstimate of thresholds?:p :D I mean was it very easy, easy, okayish, tough or very tough for you??:p :D :)

no it's like 0 is the lsb but then the number zero in digital signal corresponds to 1 like 2^0 so 1 = 2.5mv that way :p
