    Transfer functions - Complex poles

    Sorry for my mix up with terminology, yeh i understand the process of doing it but i don't know how i would do it in this scenario given that the poles are complex and I am looking for a sine or cos in the time domain response. Many thanks.

    Transfer functions - Complex poles

    Sorry i didnt explain myself very well, say you have a system whos transfer function is; H(s)= \frac{5}{s^2 + 4S + 5} When the input is a step response, the output will be a decaying sinusoid before it reaches a steady state, I would like some help in understanding how you get to a time...

    Transfer functions - Complex poles

    Yeh that is helpful thanks, i was wondering if anyone could explain it in terms of Laplace domain equations and time responses etc as that is what I am struggling with. many thanks

    Transfer functions - Complex poles

    Hi, i'm having a bit of trouble understanding how a system modeled by a transfer function in the laplace domain with no zero's and a complex conjugate pair for the poles causes an oscillation when the unit step function is applied. Any help would be appreciated Many thanks.

    Zero & Pole Plots: Filters, Frequency Response & Impulse Inputs

    Sorry maybe i wasnt clear enough, i meant plotting the information from the the transfer function(i.e. the poles and zeros) onto the argand diagram. That bit is all understood. I am just unsure about how to get from that argand diagram form to a frequency response. Forget about the...

    Zero & Pole Plots: Filters, Frequency Response & Impulse Inputs

    Hi I am after any information regarding zero pole plots, specifically with reference to filters. I understand the process of getting the transfer function and plotting it. But once its been plotted how do you go about translating that into a frequency response. I am also wondering about...

    Engineering Solving Diode Logic Circuits: 4V, B=2V, C=3V

    EDIT: I was being stupid and forgot the first diode would turn off after i worked out stuff for diode C, thanks anyway, solution found!Hi I'm having some trouble getting the correct output voltage when i model the diodes using a voltage ofset and resistors. A = 4V, B = 2V, C = 3V Using Voltage...

    Solving for C in 1.41 = |(1+1.10iC)/(1+0.1iC)|

    Okay, but I am still struggling to see how that will help me solve for C

    Solving for C in 1.41 = |(1+1.10iC)/(1+0.1iC)|

    I have the following equation below but i am unsure about the method of finding the variable C. Sorry if its hard to read. 1.41 = |(1+1.10iC)/(1+0.1iC)| Many thanks
