frequency resolution

基本解釋

In STFT is window is of finite length, and we no longer have perfect frequency resolution.
快速傅立葉變換用到的窗寬度長度有限，因此不能獲得完美的頻率分辨率。
In FT, the kernel function, allows us to obtain perfect frequency resolution, because the kernel itself is a window of infinite length.
傅立葉變換中用到的內(nèi)核窗函數(shù)允許我們獲得一個(gè)完美的頻率分辨率，因?yàn)榇昂瘮?shù)本身具有無限寬度。
DDS is an advanced technique on frequency synthesis, whose primary advantages are controlling facility, continuous phase and fine frequency resolution.
DDS技術(shù)是一種先進(jìn)的頻率合成技術(shù)，其主要優(yōu)點(diǎn)是易于程控，相位連續(xù)，輸出頻率穩(wěn)定度高，分辨率高。

The waterproof functionality doesn't come at the expense of the sound, either, with the Aquaris sporting high-definition sound with 48 channels with high frequency resolution and a 12 kHz frequency range.

頻率分辨率
It takes a muhilayer division to frequency band, and it take a further division to high frequency section that is not subdivide by multiresolution analysis. So it improved the frequency resolution.
小波包分析能夠?yàn)樾盘?hào)提供一種更加精細(xì)的分析方法,它將頻帶進(jìn)行多層次劃分,對(duì)多分辨分析沒有細(xì)分的高頻部分進(jìn)一步分解,從而提高了頻率分辨率。
