一种为防止太阳光引起激光接收机过载的电路,其反馈网络提供一直流电流以抵消二极管电流的直流电平;一种区别于通常的接收机电路设计,通过使信噪比最大来提供更高的灵敏度,并且用二重均衡处理来重建频率响应,以实现整个所需频率范围内平坦的频响。
A circuit to prevent over-loading of the laser receiver by the sun's light, the feedback network providing a direct current to counteract the DC level of the diode current; a difference from conventional receiver circuit designs that provides higher by maximizing the signal-to-noise ratio Sensitivity and reconstructs the frequency response with a double equalization process to achieve a flat frequency response over the entire desired frequency range.
