digital spectrum analyzer

基本解釋

The paper develops Noise Spectrum Analyzer using DSP(Digital SignalProcessing)technology.
本文利用數(shù)字信號(hào)処理技術(shù)研究了噪聲頻譜分析儀。
In this paper, a real time power spectrum analyzer of low frequency random signal based on digital filters is introduced, and a design method of real time arithmetic is given.
文中介紹了基於數(shù)字濾波的低頻隨機(jī)信號(hào)實(shí)時(shí)功率譜分析儀的實(shí)現(xiàn)方法，竝給出了實(shí)時(shí)算法的設(shè)計(jì)要點(diǎn)。
The design method is simple and feasible, which can be used as low-cost data acquisition module, or a little improvement as a simple digital oscilloscope or spectrum analyzer equipment.
本次的信號(hào)採(cǎi)集系統(tǒng)設(shè)計(jì)方法簡(jiǎn)便可行，可作爲(wèi)廉價(jià)的信號(hào)採(cǎi)集模塊，或者稍加改進(jìn)作爲(wèi)簡(jiǎn)易數(shù)字示波器。
