Hi Everyone,
I have some puzzle with OrCAD PSpice A/D now.
Details:
Time domain mote carlo anaylysis
Setting more settings as below

After run the PSpice program,and the PSpice program will output some data .The picture is show below.

Problem:
I want to know how the pspice program to calculate the sigma and mean deviation?

My english is so poor .So if you have any question,please conctact with me.
My email: power.yang.china@gmail.com
Thank you very much.

Re: OrCAD PSpice problem--mote carlo analysis - sigma calcul

First of all, thank wihtewiz's suggestion.
This problem is fixed by myself.

PSpice mote carlo analysis:
mean deviation calculate formula: X= (X1+X2+X3+...+Xn)/n x1...xn is a single case's deviation from nominal value.
Standard sigma calculate formula:
s^2=[(x1-x)^2+(x2-x)^2+......(xn-x)^2]/n
standard sigma is √s^2
So for a single case deviation Xn, the sigma quality is xn/(standard sigma).

If everyone have any question, please contact with me!
In another way, if your chinese is very good. Website: https://hi.baidu.com/rdtech is welcome!
