A recent article in New Scientist (page 60 of Oct 6-12, 2007 issue) claims that Oliver Heaviside invented it 30 years before Dirac. I have not been able to confirm this claim any other place, but have not looked that hard.

What is the laplace transform of a unit step function?
a pulse (dirac's delta).
How do you plot Dirac function in MATLAB?
To plot each value of a vector as a dirac impulse, try stem instead of plot.
What does delta mean in maths?
There are many meanings. The most common one is "change in". So delta x is the change in x. This form is often used in calculus where it means very small changes in x. But there is also the Dirac delta function, a fundamental mathematical underpinning for quantum physics. A delta can also be a quadrilateral which is otherwise known as an arrowhead.
What does the derivative of a function mean?
The derivative of a function is another function that represents the slope of the first function, slope being the limit of delta y over delta x at any two points x1,y1 and x2,y2 on the graph of the function as delta x approaches zero.
What is the delta function?
a2 +/- b
What are the Laplace transform of unit doublet function?
The Dirac delta function.
What is the laplace transform of a unit step function?
a pulse (dirac's delta).
Why dirac delta function is used?
Well Dirac delta functions have a loot of application in physics.... Suppose u want to depict the charge density or mass density at only a particular point and want to show that at any other point in space this density is nil, we use this dirac delta function to depict the position of this charge or mass... In general, Dirac delta function is used whenever the divergence for a field has different and contradicting values at the origin....esp used when the usual Divergence theorum is proved wrong due to contradicting values of the flux...
Form of power spectrum to dirac delta function?
The power spectrum of a delta function is a constant, independent of its real space location. It is given by |F{delta(x-a)^2}|^2=|exp(-i2xpiexaxu)|^2=1.
Is signum function differentiable?
The signum function is differentiable with derivative 0 everywhere except at 0, where it is not differentiable in the ordinary sense. However, but under the generalised notion of differentiation in distribution theory, the derivative of the signum function is two times the Dirac delta function or twice the unit impulse function.

Can a discontinious function have laplace transform?
Yes, but it can be hard to find. Some easier to find examples are: L(Dirac Delta(t-a))=e^(-a*s) L(u(t-a)*f(t))=(e^(-a*s))*L(f(t-a))
What is the birth name of Paul Dirac?
Paul Dirac's birth name is Paul Adrien Maurice Dirac.
What is the impulse response of R-L circuit?
The impulse response of an R-L circuit is an exponentially decaying signal. It represents the behavior of the circuit when subjected to a Dirac delta function input or an impulse signal. The response decays over time due to the inductor's energy storage capability.
When was Dirac Prize created?
Dirac Prize was created in 1921.

The derivative of a function is another function that represents the slope of the first function, slope being the limit of delta y over delta x at any two points x1,y1 and x2,y2 on the graph of the function as delta x approaches zero.
