The unit step function is also known as the Dirac delta function.

It can be thought of as a function of the real line (x-axis) which is zero everywhere except at the origin (x=0) where the function is infinite in such a way that it's total integral is 1 - hence the use of the word 'unit'.

The function is not a strict function by definition in that any function with the properties as stated (0 everywhere except the origin which by definition has a limit tending to 0), must therefore also have an integral of 0.

The answer is therefore zero everywhere except at the origin where it is infinite.

What is heaviside function?

The Heaviside function is a discontinuous step function. It is 0 for all values less than some specific value. At and after that value, it takes the value 1. The Heaviside function can be used to represent an "Off-On" function.See link for more.The Heaviside function is a discontinuous step function. It is 0 for all values less than some specific value.

How are piecewise functions related to step functions and absolute value functions?

A piecewise function is a function defined by two or more equations. A step functions is a piecewise function defined by a constant value over each part of its domain. You can write absolute value functions and step functions as piecewise functions so they're easier to graph.

There is no step function in Excel. However, you can use excel to create a Step Function Chart. See related links for a video to explain the process.


What is the meaning of continuous first derivatives of a function?

A continuous function is one where there are no discontinuities or step changes in the function, i.e. for a small change in input value, as that small change approaches zero, there is a progressively smaller change in output value. There are many definitions, some formal and some intuitive, for continuous functions. The definition given above is intuitive. The same definition can be give to the deriviatives or the integrals of a function. Continousness does not depend on being a deriviative or integral.

How do you convert step into ramp?

To convert a step function into a ramp function, you can integrate the step function. Integrating a step function results in a ramp function, where the slope of the ramp is determined by the magnitude of the step. This process essentially "spreads out" the step function over time, creating a smooth ramp.


What is periodicity of unit step signal?

YES, unit step function is periodic because its power is finite that is 1/2.. and having infinite energy.


Unit step signal is energy or power signal?

The unit step signal is a Power signal. Since when we find the power it comes to 1/2 (i.e finite value). And when we find its energy, we got INFINITY. If a signal has energy as infinity and power as a finite non-zero value, then it is a power signal, not an energy signal.


Why dont you just use step up transformers to power the entire world with 1little power source?

Transformers only let you trade voltage for current, or the other way around. And power, which is measured in Watts, is calculated by voltage times current. Say you have a power source capable of delivering 4 Watts. A transfomer could then turn this into 0.5 volts and 8 amps, or 8 volts at 0.5 amps - but the power would still be 4 Watts. And since it's the power (= the watts) that actually gets the job done a small source and plenty of transformers wouldn't work.

How many amps are in a circuit with 125 milliwatts and 47 ohms?

You have two known values: P and R. Recall the formula for Power: Power (watts) = I2 R Basic algebra will help convert the power equation to solve for current: Step 1: P/R=I2 Step 2: SQRT(P/R)=I


What is the function of step-down transformers?

The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of Transformers. From the generation station the voltage is stepped up to a very high transmission voltage and at the end of the transmission line it is stepped down to a voltage that consumers can utilize.
