Ok I have tried to get an expression using that substitution but I still can't figure it out.

In the second image, Rac will still be given by Ra+Rc. The right hand circuit has an extra resistor (R1) and as such the overall resistance of the circuit will be calculated using a different equation (this doesn't have any effect on Rac only on the TOTAL resistance of the circuit). As the...

Ok, I think I understand all that now but the next part of the question "sketch a labelled graph of the imaginary parts of the transform" is where I really start to struggle as I don't really know what it's asking for, do you think you could point me in the right direction as I haven't even...

Thank you very much for the welcome. The explisit expression I think is: g(t)=Sin(\omega t) Would I be right in saying that e^{-j \omega t} would be written as: e^{-j \omega t}=Cos(\omega t)-j Sin(\omega t)? and yes we do have a limited table of integrals and derivatives.

I have gone as far as doing the Fourier transform but again I'm not entirely sure that this is correct, I got: G(f) = \int^{\pi}_{-\pi}Sin(t)e^{-j}^{\omega}^{t}dt I am not sure if this is as far as I need to go or not, I tried to complete the integration by using the integration by parts...

Hi there, I have been having problems with the question that I have attached, I have given it a go but unfortunately don't have a scanner to scan any of my work in but I will post it as soon as I can. Until then I was hoping that someone would be willing to give me a worked example of a...
