In this paper the influence of a stationary white noise on the estimation of a sine-wave amplitude by means of the three-point Interpolated Discrete Fourier Transform (IpDFT) method is investigated.

Beamforming of plane-wave ultrasound echo signals in the Fourier domain provides fast and accurate image reconstruction. Conventional implementations perform a k-space interpolation from the uniform ...

Hands-On FFT of an Input Signal In this project, the Pmod I2S2 module is used, which is cheap and widely available from various sources. A signal (sine wave, square wave, or any other waveform) is ...

The equation can be written as follows: 1/v^2 * ∂^2y/∂t^2= ∂^2y/∂x^2 In this equation, v is the velocity of a wave, and the other parts describe the displacement of the wave in one direction.

Fourier Transform /* Performing FFT audio file for each time point * * timeScale is a parameter that determines the time scaling ratio. * This is the value by which 1 second of the audio file is ...

In machine learning or deep learning, the models are designed in such a way that they follow a mathematical function. From data analysis to predictive modelling there is always some mathematics behind ...

See all Abstractions blog Wavelets came about as a kind of update to an enormously useful mathematical technique known as the Fourier transform. In 1807, Joseph Fourier discovered that any periodic ...
