| 1. | There are certain differences between am and fm receivers
调幅和调频接收器有所不同。 |
| 2. | Intermediate frequency of fm receivers
调频接收机中间频率 |
| 3. | In an fm receiver , the limiter and discriminator stages are circuits that respond solely to changes in frequency
在调频接收器中，限幅器和鉴别器这两个设备仅对频率的变化做出反应。 |
| 4. | One cool feature is a built - in transmitter that can be set to relay the satellite radio signal to nearby fm receivers in your house or car
另外一个酷功能是内建的调频讯号发射器，让你可以将卫星广播的讯号传送到家中或车上的传统调频收音机。 |
| 5. | In order to ensure the normal operation of airplane navigation and communication system , you are kindly requested not to use your callularphone / cd player / fm receiver
为确保飞行和通信系统的正常操作，请您不要使用手提电话/激光唱机/调频收音机。 |
| 6. | The other stages of the fm receiver are similar to those of the am receiver but require more care in design and assembly to make full use of fm ' s advantages
调频接收器的其他部分与调幅接收器相似，但其设计和组装需要更加小心，以充分发挥调频的优势。 |
| 7. | Because the noise that affects radio signals is partly , but not completely , manifested in amplitude variations , wideband fm receivers are inherently less sensitive to noise
因为影响到无线电信号的噪音只是部分的，而不是整体出现于波幅变化中，调频宽频的接收器自身对噪音不够敏感。 |
