Fourier Series

Тригонометрический ряд Фурье
Тригонометрический ряд Фурье
A Fourier series is a mathematical technique that breaks down periodic functions into an infinite series of sinusoidal harmonics. The trigonometric ...
Экспоненциальный ряд Фурье
Экспоненциальный ряд Фурье
In audio signal processing, the exponential Fourier series plays a crucial role in sound synthesis, allowing complex sounds to be broken down into simpler ...
 Свойства ряда Фурье I
 Свойства ряда Фурье I
The exploration of the properties of the Fourier series begins with linearity. When considering two periodic signals and forming a third by their linear ...
 Свойства ряда Фурье II
 Свойства ряда Фурье II
When a signal undergoes time scaling, the Fourier series coefficients remain the same, but the representation of the Fourier series changes due to an ...
Теорема Парсеваля
Теорема Парсеваля
Parseval's theorem states that if a function is periodic, then the average power of the signal over one period equals the sum of the squared ...
Сходимость рядов Фурье
Сходимость рядов Фурье
The Fourier series of a signal is an infinite sum of complex exponentials. The infinite sum is often truncated to a finite partial sum to make it ...
Дискретно-временной ряд Фурье
Дискретно-временной ряд Фурье
The Discrete-Time Fourier Series is a counterpart to the Fourier-series expansion of continuous-time periodic signals. Calculating the expansion ...
