hi, I was wondering how can i use actual symbols like partial derviates, integration, or derivation etc etc symbols to post my questions here... thanks.

Thanks for all your replies...especially Georgepowell, whose step by step solving really helped me understand it well. Could somebody also help me in taking the partial derivate of the following expression with respect to lambda. (xln(lambda)) thanks a lot.

Thanks a lottttttttt gel...i got it right now... :-)

I tried, but not getting the right answer. Could somebody clear this confusion... thanks.

Sorry , i forgot to put the parenthesis. Here , it goes.. Hope it will be clear this time. Note that the parameter lambda has this value: lambda = (0.15*10^-5) And i was trying to calculate, (1 - e^(-lambda*y)) = 0.1 for y, and the answer is assumed to be 70,240. Similarly, 1 -...

hello, I was trying to figure out what will be the y value for this equations: 1 - e^-0.15*10^-5*y = 0.1 Could somebody help me in this?? The answer is supposed to be 70,240. thanks.

NO, i meant X-axis . I assumed that when the coordinate shift can be done on Y-axis, the same can be done on X-axis. Also, when x(t) has amplitude of (-A to +A), the book says that we can write it as x1(t) - A, where x1(t) has an amplitude of 2A. Any explanations. thanks.

So that means that an X shift can be done in the same way. For e.g -5 to +5(on the x-axis) can be from 0 to 10 on the positive side.

Friends, While studying Fourier Transforms, i saw that a square wave with amplitude +A and -A can be replaced with a sqaure wave with amplitude 2A. Just wondering how it was done? I'm new to Signals and Systems . thanks.

Thanks rbj for your detailed reply. Ever since you posted, i was reading and trying to get my concepts clear and finally almost everything is clear then before.

Can anybody prove or give a bit detail about the causality condition i.e h(t) = 0, t<0 for continuous-time LTI system. And based on this how a continuous time LTI system is causal if, x(t) = 0, t<0.

Thanks a lot rbj for your letting me know about this group. I am feeling very comfortable by having people like you here in this forum. Your helping attitude has put some extra learning desire in me. :-)

thankyou so much rbj. Infact, after reading some threads in this forum, i was expecting reply from you. I was desperately looking for a forum like this where i can find people who love to help others and are in the same boat. My background is NOT in Electrical Engineering rather in...
