The trap / detrap process is very long timescale. So the areal
effect on trapping would be frequency (still lowish, still r**and**om)
**and** not the amplitude of any individual event. I think the
**probability** of time-coincident detraps is very very low.
I'd say area moves the voltage amplitude down, **and** the
frequency axis to the (...)

The commulative density function CDF of Rayleigh is given by:
Pr(r ≤R)=1-exp(-R^2/2σ^2)
What is the **probability** of getting the value of r**and**om variable exactly equal to r?

'morning guang4243,
I've applied the technique described in the (brilliant!) book "Numerical Recipes in C" to create r**and**om numbers with arbitrary **probability** distributions with success in the past. The book is available freely on the web, **and** the section describing both the technique **and** the generation of Gaussian (...)

The joint pdf of r**and**om variables X **and** Y is
fx,y(x,y) = ? 0and fy(y).
2. Find the conditional pdf?s fx|y(x|y) **and** fy|x(y|x).
3. Are X (...)

Since r**and**om noise is in-determinant, you can not calculate the error for 1 bit. You can only say the **probability** of error.
In the 80's we could predict Soft BER **and** Hard BER on magnetic HDD's using 1 full track of 10KB ( don't laugh) **and** with delay-lines reduce the window of data recovery top measure margin (...)

I do not underst**and** your Case A.
In Gaussian r**and**om processes there is a mean value, a st**and**ard deviation value **and** the **probability** of outcomes can be calculated (likely outcomes above a value, likely outcomes between value....)
In uniform distributions there is no mean value **and** the (...)

4) you have a 3x1 vector x of three i.i.d. Gaussian r**and**om variables.
you have a matrix A which is k x 3, where k=2, 3, 4, **and** in all cases the
coefficients of A are such that its rank is the minimum between k **and** 3.
Write the joint p.d.f. of y=Ax for al the values of k.
(Note: k=2,3 are easy but k=4 requires some thought)

I'm deriving equations, **and** I'm stuck at the following.
+inf
∫ dN = ?
-inf
where N: r**and**om variable,pdf: Gaussian **probability** distribution function.
Can we express the above equation without pdf(N) or whatever we can derive?
Thanks,

Hi pakitos,
use r**and**() function. It returns r**and**om numbers uniformly distributed between 0 **and** 1.
Let x=r**and**(1);
The **probability** that x is between 0 **and** p is p (p between 0 **and** 1);
The **probability** that x is between p1 **and** p2 is p2-p1 (...)

Hello.
I made a modulator-demodulator binary PAM in a pair of FPGAs. Now, I want to test my design to find the bit error rate (or error **probability**) versus SNR.
What is a correct procedure to achive a good estimation of the BER?
my method, at this time was the following.
I generated 100 r**and**om sequences of ones **and** zeros, I take (...)

I want to send a simple signal s(t) from transmitter to receiver side we get s(t)+n(t) . For this i want convolution of two signal **and** i want to find out pdf for the convolved sequence. I am getting diffculty in representation of s(t) **and** n(t) mathametically **and** also i want inputs. please help me.

In general such problems may be caused by (in decreasing order of **probability**)
a) a bug in the code
b) a misunderst**and**ing of how FDTD is set up
c) cosmic rays flipping r**and**om bits
In your case it is a)
for i = 100, **and** j = 80,..120
you let the god of r**and**omness decide the conductivity in your (...)

I want to simulate a periodogram of a smoothed **and** averaged periodogram.
For that, I need the **probability** distribution of a such periodogram.
The averaged periodogram is a r**and**om variable of a Gamma distribution with parameters N (the number of averaged periodograms) **and** S(f)/N (S(f) is the PSD of the signal).
The (...)

Your problem comes from a simple model y=x+z, where z has a **probability** density function with the form
f(z)=kexp(-|z|/2)
**and** the underlying assumption is that x **and** z are two independent r**and**om variables, you will get the resulting **probability** density function for y as you stated.
With above (...)

My simulator doesn't support Monte Carlo analysis as Cadence. However it allows sweeping parameter values that are chosen based on statistical variations. For example, it can vary the threshold voltage VTH using r**and**om values chosen by **probability** distribution. The user provides the central value of VTH **and** its relative variation (as (...)
