Abstract : The patent pertains to a circuit for preventing laser receiver overload caused by sunlight wherein a feedback network provides a d.c. current to cancel the d.c. level of the diode current; and, a receiver design alternative to conventional designs where higher sensitivity is provided by maximizing the signal to noise ratio and processing by dual equalization to reshape the frequency response to achieve a flat response over the frequency range of interest.
