射频调谐 tuned radio-frequency
- 还在理论上分析了射频功率调谐外差频率的原理。
In addition, a theoretical analysis is made for the offset frequency being tuned by RF input power. - 为了解决磁共振成像系统中双调谐射频线圈的设计问题,提出了一个通用等效电路模型。
A generalized equivalent circuit model was developed for both single-tuned and double-tuned radio-frequency(RF) coils for Magnetic Resonance Imaging (MRI) systems. - 作者的解决这个问题是使用可调谐射频前置放大器这也渠道作为一个低通滤波器调谐88-108兆赫时,低端的带异国情调的地方大部分的谎言。
The author's solution to this problem is to use a tuneable RF preamplifier which also acts as a low pass filter when tuning the low end of the 88-108 MHz band where most of the exotic channels lie.
