The fourier coefficients calculator is an amazing online source that gives a solution of complex functions into periodic functions. You do not do manual calculations to solve these complicated questions by hand just use our tool and get a solution in less than a minute.
What is the Fourier Transform?
Fourier transform is a complex analysis method where it analyzes the functions, specifically the periodic which is composed of a combination of sinusoidal components. It is used to decomposes a function of time into its constituent frequencies from the original function
This type of transformation is commonly used in signal processing, image process, physics, mathematics, and engineering because it gives insights into the nature of a function to transform it into a periodic function.
Fourier Transform Formula:
The formula of fourier transform is denoted with a frequency function f(ω) that converts it into a periodic function f(t). The fourier transform formula used by the Fourier transform calculator.
$$ F \{ f(t) \} (\omega) \;=\; \int_{-\infty}^{\infty} f(t)e^{-i\omega t} dt $$
Here e-iωt is the angular frequency of waves during oscillation.
Evaluation Process of Fourier Coefficients Calculator:
The fourier calculator gives you an easy way to evaluate the Fourier transform function and get a solution in just one click without much effort. You just need to put your function into even complicated or lengthy functions only and get a result.
Let's see the steps used in the calculation process of the Fourier transformation calculator. These steps are:
Step 1:
Identify the given function f(x) and its limits
Step 2:
Put the given function f(x) in to fourier transform formula such as,
Step 3:
Simplify the formula of fourier transform after adding the f(x) value if possible.
Step 4:
Take the integral with respect to t because we want to convert them into a time domain function. For integration, you can use different methods to get solutions.
Step 5:
After integration, apply the limits and simplify it.
Step 6:
After simplification, you get the solution of your Fourier transform function from the frequency domain to the time domain.
You can see the below example to get further clarity about the fourier transform online calculation process.
Pratical Example of Fourier Transform:
The practical example of Fourier transform function will express, how to transform a Fourier function that is present in the frequency domain into a time domain function. It also gives you a clue how the Fourier transform calculator with steps solves such complex problems.
Example: Find the Fourier Transform of:
$$ f(x) \;=\; \biggr[ \begin{matrix} e^{-ax}, & a ≥ 0 \\ 0, & x < 0 \\ \end{matrix}, a > 0 $$
Solution:
Convert the given function into a Fourier transform formula,
$$ \hat{f} (k) \;=\; \int_{-\infty}^{\infty} f(x) e^{ikx} dx $$
The function f(x) is e-as,
$$ =\; \int_0^{\infty} e^{ikx -ax} dx $$
Solve the integral and apply the limit then your function solution is,
$$ =\; \frac{1}{a - ik} $$
