## dB magnitude spectrum....

Maple

I  Presented problems for the plot "DB magnitude spectrum."
The structure of vector data spec has the following configuration,Float (-infinity), inside.

N := 64;
T := 1;

f := .25;
A := 1;
phi := 0;
n := Vector(N, -> i-1, datatype = complex[8]);

x := cos~(2*Pi*n*f*T);

X := DiscreteTransforms[FourierTransform](x, normalization = none);...

## confidence limit of Poisson Distribution...

Maple

restart;

P := proc (x, lambda) options operator, arrow; piecewise(x < 0, 0, lambda^x*exp(-lambda)/factorial(x)) end proc;

The upper confidence limit. When the confidence limit is 95%, e is 0.05

Lu := proc (a) options operator, arrow; sum(P(x, lambda), x = 0 .. a) = 0.5e-1 end proc

Lu(10)

exp(-lambda)+lambda*exp(-lambda)+(1/2)*lambda^2*exp(-lambda)+(1/6)*lambda^3*exp(-lambda)+(1/24)*lambda^4*exp(-lambda)+(1/120)*lambda^5*exp(-lambda)+(1/720...

## vertical lines...

Maple

Is it possible to a plot,  shown in worksheet, insert vertical lines using the Builder plot ?

GRACIAS

## What is .........

Maple

What is a pulse height analyzer?
What math behind the PHA? DFT FFT?
