Hi kydong,
Adding several iid (independent, identically distributed) RV (**random** variables) get a distribution that resembles more and more a normal distribution.
It is a consequence of the central limit theorem.
The **number** of RV to be added depends on how much similar to **gaussian** has to be the resultant distribution.
Only 3 RV give a rough

BER = Bit Error Rate
For a serial data stream this give the **number** of bits which are sampled wrong due to jitter. So it is a precentage of errors.
e.g. 10e-12 means one out of 10e12 bits are wrong.
the RMS (or sigma) value is given for **random** jitter (RJ)
**random** jitter is **gaussian** and unbound (from the theory)
For a (...)

The central limit theorem of the **random** **number** theory says
that the rather large sum of any **random** **number**s gives the **gaussian** **random** **number**.
Therefore
Yoy can load any PDF file, add, say 100 neigboring bytes in it and get the
genuine Gauss **number**.

Allot of times it's like this:
The **random** function is more likely a pseudo **random** function generating outputs with a certain distribution (uniform, **gaussian**, ...).
This means that when you give the same seed, the function always gives the same outputs in the same order.
The seed is the thing which makes it "**random**". (...)

Hi, Friends,
Anyone knows the essential difference between pseudo **number** series and true **number** series?
I know that pseudo **number**s in general have a repeated pattern while true **number**s don't have. So pseudo **number**s are predictable while true **number**s is not. But what if a pseudo (...)
