So I have completed (a) as this (original on the left):
I have then went onto (b) and I have equated T(s)=Z(s) as follows:
and due to
hence
Does this look correct to you smarter people?
Thanks in advance!! All replies are welcome :)
I am assuming that it would repeat? There is no symmetry that I can see? It would be odd if there was no 'missing' parts of the wave however
Thanks for the reply
Hi HDG,
Did you get the question correct? I got a final answer also of 97.271%
How did you select the fields to create the scattergraph?
Thanks for any help!
ANY AND ALL HELP IS GREATLY APPRECIATED :smile:
I have found old posts for this question however after reading through them several times I am having a hard time knowing where to start.
I am happy with the sketch that the function is correctly drawn and is neither odd nor even. It's title is...
Hi again Rudeman,
Was looking over my old working and found that in the final line of working is incorrect, unless I'm just being an idiot!
= √ (31491.630+j9511.802)
= 179.427+j26.506Ω
Just to update this post.
@FactChecker I think you give the materials too much credit, time and again I find inconsistencies or incorrect parts. Thanks for your help, it is much appreciated!
@FactChecker Yeah in the materials the first graph is even (FIG.1) and the second graph (FIG.2) which is FIG.1 'shifted' is now odd, however I would say that it is neither odd nor even, unless as you say it is shifted down the 'Y' axis. There is however no mention of this Y-axis shift in these...
Hi @bobob thanks for the help that really clears things up! I have tried bulking out the answer for each as follows, does that look correct to you? ( I realise this just builds on what you wrote )
a) Function is neither odd nor even.
a0= V/2, an=0
b) Function is even hence will only...
I thought it wasn't odd, the learning materials seem to be incorrect, it is implying that the diagram shown is odd - seems to be a recurring theme with this learning materials!
@FactChecker Thanks a lot for the insight, not sure how I messed up the A0 figure. I have one query regarding a similar waveform in the learning materials that has been 'shifted odd' and I am unsure how this wave is 'odd' and not neither? wondering if you can give some insight. Thanks again.
Ah I see what you mean I think, so I could maybe say the following:
- The wave is neither odd nor even
- a0 =0 & an = 0
Surely that can't be all there is?
@Connorm1
Hi all, having a look at this now and I am on the same boat as you were - I don't know how much detail they want and where to start with part (b). I see that you were trying to move the wave down the Y-axis to make it Odd, why not shift it to the right by T/4 so that it creates an...
Hi Babadag,
I would've likely said the same however in my learning materials the below is stipulated. I then equated that each as appropriate. Any ideas?
Homework Statement
Figure shows a 50 Hz, high-voltage, transmission line. The relationships between the sending and receiving end voltages and currents are given by the complex ABCD equations:
where 'S' stands for sending-end and 'R' stands for receiving-end
(a) Given the parameter values...
I'm trying to do this but can't seem to work it without a value for the voltage source.
So i made the three nodes at the top V1, V2 & V3 and made the following equations
V2/13 - V3/13 - V3/100 = 0
V2/13 - V1/13 - V1/75 = 0
V1/13 + V3/13 - V2/213 - 2*V2/13 = 0
Struggling to move on from...
