thanks a lot so if I understood you right i start with LAPPLACE and I go on with the rest, thanks a lot of replying and for the book tip.

hi i wanted to know if anybody that knew about dsp and all the Fourier series and transforms had any advice on how to master it ... very swiftly..

BJT current issue help urgent hello i have a problem with current and the convention and so on. bottom line for a bjt my professor said that Ie = Ic + Ib but the next slide he remixes it telling us that and i quote " the relatively large current flowing from the emitter to the collector is...

hello, while doing the mesh analysis what do you substract to what to get the current that is in the middle of two loops what is the rule to get i1 - i2 or i2 - i1 it depends on what ? thanks in advance for the help :smile:

crystal clear tx a lot for the help : )

thanks a lot. But then who is right? if i get a negative voltage or current do i take the absolute value because the polarity that i chose was wrong? tx for the help
