unwanted signal 中文意思是什麼
unwanted signal
解釋
干擾信號, 不需要的信號-
Since the envelope of modulated signal fluctuates, these methods generate unwanted intermodulation distortion ( imd ) products in a nonlinear radio frequency ( rf ) power amplifier ( pa ). so it is necessary to use linearization technique to reduce the adjacent channel interference ( aci )
但包絡變化的調制信號經過非線性射頻功放后會產生交調分量，因此必須採用線性化技術來減少由此產生的鄰道干擾。 -
Bits transmitted by every subchannel are determined by its value of signal to noise ratio ( snr ), and the unwanted power caused by noise is distributed to every subchannel, so their damage is weakened
它根據各個子通道信噪比的情況確定其傳送比特數，由噪聲引起的干擾功率被分散到各個子通道中，降低了其引起的干擾。 -
In television, an unwanted component in the picture signal output from a camera, caused by the scattering of light in the optical system
電視中來自攝象機的圖象信號輸出中不希望出現的組成部分，它是由光學系統中光散射引起的。 -
Mask the signal set with the unwanted signals
用不必要的信號屏蔽信號設置。 -
Unwanted electrical energy in a circuit that is unrelated to the desired signal, s - ources of noise are most often generated by some type of switching circuit, common sources include switching voltage regulators and clocked sighals such as digitol crcuits
指在一電路中與所要訊號無關的多餘電能，雜訊的來源通常為某些形式的切換電路，常見的雜訊為切換式電壓，調整器及時脈訊號，如一些數位電路。
