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 ...

スペクトルとは？科学・音響・通信における「スペクトル」の重要性と応用 スペクトルとは、複雑な信号やデータをその成分に分解し、成分ごとの強度やエネルギーを波長や周波数の順に並べたものです。これは、光や音、電磁波などの波動現象を分析する ...

Abstract: In the popular music market, the music producer takes a large amount of time and effort to produce one piece of decent music. It would be much more productive and efficient if music ...
