I saw in a question related to Signals and systems that the limits were taken from 5- to 10+ where the signs were in the feet of the numbers..lol..i don't know what you call that. What does this mean?

Can someone explain this sentence in MOSFET design.. The Since the drain will be at a positive voltage relative to the source the two pn junctions can be effectively cut off simply connecting the substrate terminal to source terminal.

Please can someone explain the clear concept between large signal model and small signal models in BJT. Please explain what to assume in large signal and small signals problem solving wise and also the concept. Amongst vBE, VBE, vbe which is large signal?, small signal? and what we assume in...

Wait, Can we apply BIBO for non-linear functions like this one? Ps i have edited my prev post, i mentioned incorrectly what i had found.

Yes :-p i finally proved it myself, as t-> infinite the output will also become bounded ie 1. Both books are wrong...

I have two books as reference and they both say e to the power -x[n] is unstable. They take x[n] and y[n] in terms of impulse and impulse response and prove that for n=0 we have output e^-1 and for n/=0 it is 1. Then it uses the bibo stability condition for causal and stable system and prove...

what about x[n]?

Is exponential function e to the power x[t] stable? My book uses BIBO and says its stable but for -x[t] it says its not stable. Is my book wrong?

Thanks..

Why is it necessary for the gain magnitudes of inverting and non- inverting ends to be equal in magnitudes to be able to reject the common mode signal? Also can someone explain the ratio obtained of voltage divider in difference amplifier. R4/R4+R3[1+R2/R1]= R2/R1 Where, R1 input resistance...

Exactly. Atleast 40 to 45 percent of the paper is based on old papers and even some questions are repeated again and again. This encourages cramming... This comment made me recheck on google if there are other countries in world called 'India'. How many India's are there in the world? I am...

Look first of all, holes can't really do anything even if they are attracted by terminal. Look it the other way, its the electrons that move and generate holes. Now having said that first look at the frwd bias condition. Now we know that the depletion region is formed of two polarities of atoms...

I am too from India, although i did my schooling from Dubai. I too crammed up various topic when i was in senior school, that's what i mean by the same boat theory. Every single CBSE school in India doesn't enforce practical ways of teaching. There's a large chunk of population that just...

Smart_Worker is probably from India by the 'Same boat theory'. I understood this just by reading the question. :D I keep hearing it all day long...yawns..

Divergence theorem just makes it very clear. What is flux? Product of normal component of vector field and the surface element. What is divergence of vector field? Net flux diverging per unit volume. What is Divergence? Positive or negative divergence of a vector field at a point...
