## How do you define a rectangular pulse?

[rektagylr pls] (electronics) A pulse in which the wave amplitude suddenly changes from zero to another value at which it remains constant for a short period of time, and then suddenly changes back to zero.

## Is a rectangular pulse periodic?

The pulse wave is also known as the rectangular wave, the periodic version of the rectangular function.

## What is the total power of rectangular pulse?

The total energy of the rectangular pulse can be found by integrating the square of the signal. Basically energy is given by area under the curve.

## What is the function of rectangular?

The rectangular function is a function that produces a rectangular-shaped pulse with a width of (where in the unit function) centered at t = 0. The rectangular function pulse also has a height of 1.

## What is a rectangular function used for?

The rectangular function can often be seen in signal processing as a representation of different signals. The sinc function, defined as , and the rectangular function form a Fourier transform pair.

## What is the function of a rectangle?

Function Description
CopyRect Copies the coordinates of one rectangle to another.
EqualRect Determines whether the two specified rectangles are equal by comparing the coordinates of their upper-left and lower-right corners.
InflateRect Increases or decreases the width and height of the specified rectangle.

## How do you define a rectangular function in Matlab?

The rectangular pulse function is also called the rectangle function, boxcar function, Pi function, or gate function. … Rectangular Pulse Function

1. If a < x < b , then the rectangular pulse function equals 1.
2. If x = a or x = b and a <> b , then the rectangular pulse function equals 1/2.
3. Otherwise, it equals 0.

## What is rectangular waveform?

[rektagylr wv] (electronics) A periodic wave that alternately and suddenly changes from one to the other of two fixed values. Also known as rectangular wave train.

## What is Fourier transform in signals and systems?

The Fourier Transform is a mathematical technique that transforms a function of time, x(t), to a function of frequency, X(). It is closely related to the Fourier Series. If you are familiar with the Fourier Series, the following derivation may be helpful.

## What do you mean by Fourier transform of delta function?

The Fourier transform of a function (for example, a function of time or space) provides a way to analyse the function in terms of its sinusoidal components of different wavelengths. … The Dirac delta function is a highly localized function which is zero almost everywhere.

## What is Fourier transform of impulse train?

As you just saw, p(t) is an infinite train of continuous time impulse functions, spaced Ts seconds apart. … Thus, an impulse train in time has a Fourier Transform that is a impulse train in frequency. The spacing between impulses in time is Ts, and the spacing between impulses in frequency is = 2/Ts.

## How do you create a rectangular pulse train in Matlab?

y = pulstran( t , d , func ) generates a pulse train based on samples of a continuous function, func . y = pulstran( t , d , func , fs ) uses a sample rate of fs . y = pulstran( t , d , p ) generates a pulse train that is the sum of multiple delayed interpolations of the prototype pulse in vector p .

## What is the ACF of a rectangular pulse of duration T is?

Explanation: The auto-correlation function is the method of correlating the various instants of the signal with itself and that of a rectangular pulse of duration T is a triangular pulse of duration 2T.

## What are the properties of Fourier transform?

## How do you write a function that represents the area of a rectangle?

To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

## Is area of a rectangle a function?

This area is a function of x, the position of the moving line. … Notice this is huge that because the width of each rectangle you sweep out is 1, the area of each rectangle which is given by height times width is the same as its height because anything times 1 equals itself.
