broad band noise 中文意思是什麼
broad band noise
解釋
寬帶噪聲-
Design of microwave ultra - broad band low noise amplifier
微波超寬帶低噪聲放大器的設計 -
Testing hearing aids with a broad - band noise signal
助聽器的寬帶噪音信號測試 -
The experiment results show that the single frequency noise can be reduced 7db ( a ), and the broad - band random noise can be reduced effectively in assigned frequency band
實驗對單頻噪聲取得了7db ( a )的降噪效果,對寬頻噪聲則能在指定頻帶上取得較好的降噪效果。 -
We find that the noise level of the record is very low. even in weak ground motion condition the digital broad - band record has high signal - to - noise ratio when the period is as long as 20 sec. the signal - to - noise ratio of the velocity - type records is lower than that of the acceleration - type records
木義發現,數宇寬頻帶記錄的啪盧水平很低,在川朔k達205時,即仗在弱地震動的惰況下,還具有較高的信啪比,並且濁度型記錄的信噪比禾廠加讓度型門錄的信噪比。 -
The reliability of the observation data in long period range is particularly inspected. this is done " by verifying the instrument response characteristic, examining the signal - to - noise ratio, comparing the recovered ground motions and response spectra from the velocity type and acceleration type digital broad - band records
對于速度型和加速度型的數字寬頻帶記錄,從儀器特性、恢復的地面運動對比、信噪比研究、反應譜對比等方面研究這類記錄在長周期段的可靠性。
