With the ever-expanding adoption of wireless in embedded systems of all types, there’s no question that having spectrum analyzer capability in an oscilloscope is a time-savings convenience for ...

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 ...

A set of functions are presented for Octave/MATLAB that allow easy, consistent, and properly scaled DFT/FFT analysis of signals and noise. The techniques and functions presented are easily translated ...

What is real-time spectrum analysis? Spectrum (FFT) vs. real-time mode for viewing spikes. What is needed to test for conducted and radiated emissions? If you’ve ever tried to perform ...

The Zoom FFT is interesting because it blends complex down conversion, lowpass filtering, and sample rate change through decimation in a spectrum analysis application. The Zoom FFT method of spectrum ...
