The Light Emitting Diode,tral line width. The communication engineer is aware of the desirability of a signal source which is monochromatic. Such a single frequency source may be modulated and can act as the carrier of a high concentration of information. On the other hand, a wide bandwidth source would not be suitable for从容 发表于 2025-3-25 01:27:56
,Solid State Photodetectors — The Photoconductor,perates on a low bias voltage, and responds over a wide range of wavelengths depending on the material chosen. The photoconductor has the potential of high current response since its gain factor may be larger than unity, provided material parameters are chosen carefully. Besides infrared detection,
