    Transmission line charateristics measurement?

    Thanks for your reply Bob :-) Yeah 7-core wire is good for mechanical strength nt for transmission, but I am using it for transmission purposes as well. Ta, T

    Transmission line charateristics measurement?

    Thanks Guys, your replies are very useful :-) Sorry for a bit of correction, C=1.8uF not C=180uF. It is a 7-core wire but I am using 2-cores as twisted pair. The capacitance is calculated with respect to 6-cores+an armour on these cores. Velocity factor is 0.66, it is #22 AWG, each core is...

    Transmission line charateristics measurement?

    Thanks 4 ur reply :) You are right the oscilloscopes have poor resolution, I did see this limitation for TDR. Unfortunately the oscilloscope I have dont have TDR built in. I wonder if a resistive load will be ok for TDR? The other method seems very easy, using LCR for characteristic...

    Transmission line charateristics measurement?

    Transmission line charateristics measurement?? Dear all, I want to do cable analysis of a 3800m long twisted pair wire to set up a communication system. It is not usual twisted pair wire (telephone), has different impedance, R=194, L=4mH, C=180uF. The things to be analyzed are...

    Maximum of two correlated random variables

    Hi, Thanks Pere. I dont have their joint dis 'f'. Its difficult to get JPDF of correlated non gaussian variables (not sure how to get). What all I have is varaible A & B given as, A=a0+a1x+a2x^2+a3y+a4y^2 B=b0+b1x+b2x^2+b3y+b4y^2 where x & y are two parameters which are correlated non...

    Maximum of two correlated random variables

    Hi all, I want to find maximum of two random variables which are correlated and are non gaussian too. Baiscally I need an analytical orr approximate solution to their bivaraite distribution with means and varaince of resulting distribution. There is some work by Clark 'The greatest of finite...
