The objective of the thesis is to explore the noise sources in PLL and find the proper circuit structures to reduce the noise effects. 本文的目的是研究目前應用最廣的電荷泵鎖相環(huán)的噪聲特性以尋找減小環(huán)路噪聲的電路架構。
A vector-hydrophone array simulator can generate the target radiated noise and the ambient noise.Its application can effectively shorten the developing cycle of a digital sonar. 模擬器可以模擬實(shí)際海洋環(huán)境中目標的輻射特性和噪聲特性,應用模擬器可以有效地縮短聲納的研制周期。
