    Divide and Conquer, Matrix Multiplication MATLAB

    If there is any reason in particular that people find it difficult to answer my question, please let me know. I would be more than happy to provide additional information, and I would hugely grateful to anyone who could offer to help.

    Divide and Conquer, Matrix Multiplication MATLAB

    Problem Statement We are asked to use the following divide and conquer algorithm to get the solution for the multiplication of some matrix A and some matrix B. (See below) Consider the matrix sizes. Comment the total computational time used on the following three algorithms, when different...

    Finding the transfer Function of a Voltage Buffer

    Thanks a lot to both of you for the information that you have provided! I should be good now, if I have any more questions I'll ask my lab instructor : )

    Finding the transfer Function of a Voltage Buffer

    Thanks a lot, we're actually just beginning to scratch that unbearable uncertaintly of non-idealised op amps. And considering this is a something will be be demostrating in the lab (and considering you repeatedly said only for ideal op amps); I'm wondering what you think the effect will be with...

    Finding the transfer Function of a Voltage Buffer

    This is the circuit that I'm trying to work with. Essentially, as far as I can see it's a voltage divider connected to a voltage follower. I have the output of the first op amp as: H(s)=S1/In1= 1/10 = 0.1. However I'm not sure if there are how to obtain characteristics of such a simple...

    Analysing Non-Inverting Op-Amp Circuit: Questions & Answers

    Thanks to both of you for responding. The lab was just connecting a board with jumpers and using an oscilloscope to evaluate the gain and the phase shift. So from what I've gathered: The odd symbols for the resistors was two resistors in parallel. And thanks especially for the tip to start...

    Analysing Non-Inverting Op-Amp Circuit: Questions & Answers

    I'm supposed to be analysing this circuit to go with my lab report. However I haven't seen a circuit like this. First off I'm not sure what the symbol is on the top left resistor (15kΩ//1.2kΩ) means. Secondly I'm used to doing inverting op amps and they generally don't have many/ any...

    Help Measured vs Calculated - Frequency Response

    Weird, I suppose I'll just have to include that in my report, thanks for your help. Here's your internet!

    Help Measured vs Calculated - Frequency Response

    So it is the angular frequency, that clears up what was wrong with my assumption about my equation being wrong, do you know anything about pSpice and why my gain might be different?

    Help Measured vs Calculated - Frequency Response

    I have a huge difference between what I'm measuring and what I'm calculating, since I can no longer check the circuit (and everyone in the class seems to be having the same problem as me) I'm going to assume it's the calculations. I'm trying to calculate the response of the voltage over a...

    Finding a Transfer Function using Laplace

    I'm trying to find the Transfer function of the circuit below so that I can draw the Bode plot for it. I chose to use Laplace because I think it made it a little simpler. My equations so far: KVL of Left Loop: EQUATION1 Vs=I1(900+1800)-900I2 KVL of Right Loop: EQUATION2...

    Engineering Solving a second order circuit with phasors

    I did 4 KVL's and a KCL (because I couldn't find a relationship with the source current). The KCL is the middle node of the, between the transformers. Got the same result. Yeh I saw him solve the similar one, just brain farted and started multiplying voltages and currents to get voltages lol...

    Engineering Solving a second order circuit with phasors

    I made the relationships with the transformers first. Image of the work: And then did 3 KVL's for the last three loops. I just looked at my work though and I think I made an incorrect relationship with the current of the source loop. Just to make it less confusing i1 is the current of...
