Thanks uart. Tried that and it does show on the analogue response differently to what I was doing before.

Yep thanks :smile: Sloping rise, overshoot, comes down to 1V and then remains constant at 1V until the fall, which is a sloping fall (not steep) and there is a dip before it comes back upto the 0V.

I created the following: in ISIS. But you're right, my input/output are the same :frown: If I understand correctly what you explained above, I should be a getting a step response with a sloping rise and then a straight line ahead once it reaches the peak.

Oh I see, so basically what you explained about the rising/falling slopes is what the book was implying when it says 'describe the filter response to a unit step'. I honestly wouldn't have know because this is what I got in ISIS: http://i.imgur.com/nRCKQ.jpg As you can see, it's a...

Hi guys, what does it mean to observe a filter response to a unit step? The book gives a transfer function and I've recreated it in Proteus ISIS. Now it asks me to simulate a square wave as an input (i used a pulse generator), and then observe a filter response to a unit step, describing the...

Yep, I was initially getting confused with how to find the imaginary roots for this function - but with the help of others on this thread I corrected my mistakes, and then worked from there. Also, won't the characteristic modes of the differential just be the roots of this function (the same...

oops (λ3 + 6λ2 + 15λ + 15) * Ceλt = 0 so that means I now have to solve for λ: λ3 + 6λ2 + 15λ + 15 = 0 can I use the same factorisation as was done when trying to find the inverse laplace (Earlier on in this thread) or do I have to factorise this differently?

thanks :smile: I'm onto the next chapter now, and this same question is repeated but this time the question asks me to find the characteristic modes of the above equation. What I did: Vout = Ceλt so for the differential equation: (λ3 + 6λ2 + 15) * Ceλt = 0 then to determine λ: λ3...

Will do :smile: I hadn't thought about this before - will test it out and see how the results change. So in other words: 15Vin(s) = (s3 + 6s2 + 15s + 15) Vout(s) ?

Hi guys :) I'm going through some prep. work for my modules in Fall and I've come across a question I'm having some difficulty with. Homework Statement The question has a transfer function for which I need to find the differential equation relating the output voltage and the input...

Apologies if double-posting is against the forum rules, but I had a question related to this transfer function. I've made an ISIS circuit for this transfer funtion as in this website: http://sim.okawa-denshi.jp/en/Sallenkey3Lowkeisan.htm and the question asks for a differential equation...

Thanks, read most of that article (still trying to get some parts of it pinned down).

Thanks! This simplifies things a lot...I initially did it another way, but I'll try it this method. Definitely looks more organized.

The question's listed as a tough one in the book i.e. If I can solve this then I should have no problem in my Electronics Signals Analysis module. Which is why I figured I would give it a shot after I went through some of the other examples in the book. :smile: It's part of a big question with...

Ok I will go through my work again, I must have done some part wrong. I didn't get any sines/cosines the first time I attempted it. Thanks for the clarification.
