Fourier series is a fundamental part of mathematics. Fourier series is a commonly asked section of questions that come for many competitive exams. The Fourier series is also very important for mechanical engineering exams. Understanding what a Fourier series is crucial. If a student understands the concept and can apply the formula and principles. Applying the Fourier series in the sums then they will be able to get good marks. That is why the article has discussed the Fourier series definition for a better understanding. The Fourier series deals with sinusoids that are in harmony. The summation of weightage is also considered.
Fourier Series
Fourier series is classified as a periodic function. The summation feature is also important in the Fourier series. A Fourier series is also considered an expansion of another function. That function is periodic. A periodic function is another well-known part of mathematics. It represents f (x). In the Fourier series, different kinds of relations between cosines and sines are studied. The computation of the Fourier series forms the basis of inquiry in competitive exams. Students have to solve for the Fourier series. Understanding what a Fourier series is crucial. If a student understands the concept and can apply the formula and principles. Applying the Fourier series in the sums then they will be able to get good marks. The computation done in a Fourier series is harmonic analysis. There are certain elements to the Fourier series which are:- Coincides with orthogonal system
- It can be summarised in a short form
- It can yield any technical analysis
- It follows the universal concept of the superposition principle
Fourier Series Formula
The Fourier series formula is the key to solving the complex Fourier series. Learning the Fourier series formula is important to achieve full marks in this section. The Fourier series comes repeatedly every year for GATE exams. The Fourier Series formula yields the situation where n, p is not equal to 0 and dc v represents another well-known element which is Kronecker delta. It is represented as:- sin (v s) sin (f s) d s = dc v
- cos (v s) cos (f s) d s = dc v</sub.
- sin (v s) cos (f s) d s = 0
- sin (v s) d s = 0
- cos (v s) d s = 0
- Time scaling and linearity
- Time reversal
- Differentiation and Frequency Changes
- Conjugate symmetry
- Time shifting
