noisy circuit

基本解釋

By using closed-loop feedback circuit weak signal can be picked up from noisy background.
采用閉環(huán)反饋電路，可使系統(tǒng)從環(huán)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(diào)節(jié)器產(chǎn)生一個(gè)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(xù)使用模擬視頻的原因包括：很容易獲得低成本電路設(shè)計(jì)、可以使用低廉的銅線纜，以及在嘈雜的環(huán)境中模擬視頻性能的下降比較平緩。
