The Fourier series is a frequency-domain representation of a continuous-time periodic signal. What about aperiodic signals? The concept of Fourier series can be extended to the Fourier transform, ...
Fractional transforms extend classical integral transforms by introducing a continuous parameter that governs the interpolation between time and frequency domains. The fractional Fourier transform ...
Signals that carry information play a central role in technology and engineering — signals ranging from sound and images to sensors, radar, communication, MRI, ultrasound, touch-screens, GPS, and ...
