there are not really called functions ... rather generalized function and derivatives are called generalized derivatives.

it would be great if you could make that generalisation more lucid...actually i am stuck and thinking of finding it other way..

dw:1346491565254:dw this is your step function f(t) = u(tt_0)

the derivative at t=t_0, would be delta(tt_0)

yeah ... that works as a switch.

how you define derivative at 0?
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.1
exactly that works as a switch with constant supply

experimentX Group TitleBest ResponseYou've already chosen the best response.2
at 0, the derivative will be equal to ... value of jump times delta(t)

ghazi Group TitleBest ResponseYou've already chosen the best response.1
well don't we count for jump..i mean definition of derivative

experimentX Group TitleBest ResponseYou've already chosen the best response.2
at this particular case ... you jump is just 1

your slope is infinite ... so this acts as inpulse. there a very nice course from mit ocw. particularly exercise.

slope is zero i guess

it's a horizontal line

experimentX Group TitleBest ResponseYou've already chosen the best response.2
at zero ... you have infinite slope
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.1
impulse function has infinite slope at zero....actually point of confusion arises when i apply this concept in electrical circuit how come they consider derivative at zero or may be i am not able to correlate that properly

working with Green's functions?
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.1
no..working with impulse ramp and unit step function....i feel contradictory

okay ...i'll have to check this out
