One of the more challenging tasks facing test engineers is the creation of stimulus signals to exercise a PCB prototype or silicon turn, or to define complex high-frequency modulated signals for RF ...

This MATLAB script provides a simple demonstration of audio encryption and decryption using the Fast Fourier Transform (FFT) technique. The script takes an input audio file, divides it into blocks, ...

This project demonstrates how to reduce background noise from an audio recording using frequency-domain filtering techniques based on Fast Fourier Transform (FFT) in MATLAB. In real-world environments ...

This video shows how to use the FFT function of RIGOL oscilloscopes. The FFT function allows the user to measure the frequency and time domain of the signal waveform, at the same time. In this ...

In the process of debugging and validating both digital and RF designs, the oscilloscope Fast Fourier Transform (FFT) function and a variety of other math functions can prove valuable to designers ...

Abstract: In this work, we analyze 2D-FFT FB as an alternative waveform to OTFS. By employing part of the OTFS codification, specifically part of the Symplectic Finite Fourier Transform (SFFT), the ...
