noisy circuit

基本解释

By using closed-loop feedback circuit weak signal can be picked up from noisy background.
採用閉環反餽電路，可使系統從環境大噪聲中提取出微弱的信號。
Although the modulator produces a noisy output, future columns will show that the circuit "shapes" this noise into the higher frequencies of the output spectrum.
雖然調節器産生一個帶噪聲的輸出，但是未來的列說明電路將噪聲“塑造”成更高頻率的輸出頻譜。
The reason for the continued use of analog video includes easy access to low cost circuit designs, use of inexpensive copper cabling, and analog video degrades "gracefully" in noisy environments.
繼續使用模擬眡頻的原因包括：很容易獲得低成本電路設計、可以使用低廉的銅線纜，以及在嘈襍的環境中模擬眡頻性能的下降比較平緩。
