本质上，频谱分析仪就是一台“把信号从时域拆成各个频率成分”的功率测量仪：横轴是频率，纵轴是每个频率上的电平 ...

The purpose of the project is to analyze and monitor the radio signal spectrum wherein its FFT is calculated which is displayed in a graphical LCD. The method of analyzing the spectrum of an input ...

RF signal observation has evolved from yesteryear’s spectrum analyzer to today’s RF recorder. Swept spectrum analyzers, FFT analyzers, and real-time signal analyzers all had limitations. Today’s RF ...

Spectrum Analysis is a very broad topic. In this article we intend to address real-time bandwidth and overlap processing. Since everyone knows what we mean with the expression “real-time”, we are not ...
