| Title | The FSK / PAM applications in opticfiber communication systems | ||
| Keyword | |||
| Abstract | As the fiber being used more and more frequently, the fiber communications is an global important trend. That¡¦s why we plan to combine with analog signal PAM (Pulse Amplitude Modulation) modulation circuits, FSK (Frequency Shift Keying) and demodulation circuit OTL ( Output Transformer-Less) amplifier, and connect MP3 players or speakers. We make use of the differences of FSK & PAM signal modulation and demodulation, as backbone of the transmitter and the receiver signal transmission, to compare these two outputs of analog signals. Not only can transfer 20Hz to 20KHz frequency range between various sound sources, but also to be able to adjust the size of the volume, during the optical modulation and demodulation process, in case of on distortion, capable of transmitting 25KM distance without interference. |
