I have been asked to solve the actual load flow distribution in a given power network using two iterative methods. I have chosen Jacobi and Gauss Seidel. we have to use MATLAB to find where the solution converges. I am fine with all of this, but we have been tasked with providing graphical...

Ok, that makes sense, I have just assigned a number to n and m as it makes it easier for me to follow the logic and it calculates as you would expect. Thanks for the help guys, much appreciated!

Hi guys, I sure this is an astonishingly dumb question, but I am new to embedded systems, so don't be too harsh. I am taking embedded systems in final year at uni and working through some introductory tutorial sheets. One question asks; -If two n-bit numbers are added together, what memory...

part of my reply is contained within the quote (paragraphs 2,3,4 and 6 to be precise)

Sorry, forgot to mention... obviously I was taking n to be 2

As for course material, I have absolutely none, not even a link to a website. It is a level 5 module, so I suppose that I am expected to just get on and research, however I have a lot of family life getting in the way at them moment and can't afford it as much time as I would like. Item Budget...

Hi guys, I have been tasked with the following question; The company has set a fixed budget for Period 1 of the financial year using the following figures as being 100% of the budget: Material costs £200 000 Labour costs £100 000 Variable overheads £50 000 Fixed...

"Correct. But C1 is a second high-pass filter. What value do you intend for it? And question: is it a good design if the cutoff frequency varies with the load resistance?" C1 in my understanding, A) Blocks DC voltage B) Sets the cut-off frequency I have only concerned my self with...

Ok, first of all, I have basically started again, I have recalculated all component values (prior to going through your points) and what I get is; a gain of approx. 16... currently I am happy with that, however, the output waveform is heavily distorted in the positive cycle, which suggests to...

According to my limited knowledge and my brief teachings, this is what I am working with; Rin=1KOhms For this, my belief is; Rin=(R1llR4)llR3 I know that considering the values in the attached image my Rin would not equal 1K. I have been experimenting with different values and...

Apologies if it wasnt clear enough, U3 is an ammeter, thing connected between b and e was a voltmeter, same as R5... emitter cap was removed as I had removed it to check output signal waveform. All peripheral equipment is now removed, so hopefully you will find it clearer. What I seem to...

First pdf was not very good quality, this is includes some formulae that I have used.

Here is an image attached as a pdf, hopefully you are able to open it.

The outcome is: design a single stage amplifier with the following parameters: Rin=1KOhms Rout=1KOhms Voltage Gain=15 corner frequency=300Hz specified Transistor is BC109BP AC supply, 0.5V DC supply 20V supply frequency, not specified, I have assumed 1K We have not been given...

I am trying to design a 24V dc to 230V ac inverter operating at 50Hz. So far, by using multisim to simulate the circuit I have been able to achieve these parameters but my output is essentially a square wave. I am using a variation of a circuit that I have found on line, and I am now trying...
