摘要

12db SINAD(信号加噪声加失真比与噪声加失真比)是模拟调频接收机灵敏度的标准度量。电子工业协会(EIA)在1982年修改了调频接收机的标准。在更新后的标准中，EIA更改了用于测量SINAD的设备的规格。这一变化有效地改变了12db SINAD的定义。作者研究了这种变化的程度及其对调频接收机测量的影响

When 12-dB SINAD is not 12-dB SINAD (land mobile FM receivers)

12-dB SINAD (signal plus noise plus distortion to noise plus distortion ratio) is the standard measure of analog FM receiver sensitivity. The Electronics Industries Association (EIA) modified its standard for FM receivers in 1982. In this updated standard, the EIA changed the specifications for equipment used to measure SINAD. This change effectively changed the definition of 12-dB SINAD. The author examines the extent of the change and its effect on FM receiver measurements.<>
