    Parameters of xlpe underground cables which are used for 13.8 kV power lines

    Hi! I am studying medium-voltage cables for a project and I have a question.I am running a simulation program for cables and it doesn't allow me to combine armour with jacket.I want to simulate cables like N A2XS( F)2Y and I can't understand if it's copper screen (wires and tape) refers to...

    VDE DIN Standards for medium voltage cables

    I am looking for vde din standards for medium voltage cables. I want the characteristics - dimensions for the screen and other layers that these cables consist of. I think that VDE DIN 0276 is the one I have to find. Can anyone help me?

    gate width - cmos technology

    Hi, does anybody know the minimum gate width in cmos08??Which design rule is about that dimension? (r201)? For example, in cmos12 i think that the minimum gate width is 4lamda = 2,4 um.

    Which opamp model in Psipice should I use to study the effect of slew rate?

    Hi! I am trying to study the effect of slew rate on the output of a buffer , for different values of frequency and amplitude (of the input).As an input I use a rectangular pulse(VPULSE).Does anyone know which model of opamp I should use on Pspice ? I tried to use LM741 but I think it didn't...

    Problem with the output of an integrator

    I am trying to run this circuit on pspice.I use a square wave as input.The output should be a triangular pulse.Does anyone know if there is a mistake? Thank you

    Pspice - Saw tooth / Vramp

    Thank you very much!It worked! Added after 21 minutes: shall i use the same part (vpulse) in order to generate a rectangular pulse? is there any better way?

    Window Length to Distinguish Sinusoids

    I am trying to estimate the length of a rectangular window that is needed in order to distinguish the peaks of 2 sinusoids.For example : signal x[n]=exp(i*w1*n)+exp(i*w2*n). Can anyone help me? I found that https://ccrma.stanford.edu/~jos/parshl/Analysis_Window_Step_1.html but I think I cannot...

    equalizer / pspice simulation

    i am trying to study the frequency response of the parametric equalizer that is attached.I tried to do the simulation using pspice but i don't know if there is something wrong with my project . (that is also attached).Can anyone help me?

    upper limit of the gain of a darlington pair

    darlington pair Does anybody know if there is an upper limit of the gain of a Darlington pair??For example,if b1=100 and b2=250,is it possible to have a darlington pair with gain β=100*250=25000??

    active high-pass filter design - chebyshev 7th order

    Thank you very much!They were really flexible about the ripple and cut-off frequency.So I can choose any of these.I do have a spice simulator so I could run any schedule.However,i chose to use a sallen-key topology.I hope that it's not a bad choice.
