Bengalese finch song analysis is essential in bioacoustics for studying avian communication. Spectrograms visually represent audio signals, displaying frequency content over time. When a finch sings, ...

Radio frequency (RF) spectrogram analysis for indoor human activity recognition has traditionally relied on supervised learning with larger labeled datasets. We present a novel framework that employs ...

Abstract: Frequency Modulated (FM) signals are usually characterized by two or more components having different waveforms and time-dependent frequencies. The estimation of the instantaneous frequency ...
