摘要：A receiver circuit for receiving a modulated optical signal and for generating acorresponding electrical signal compises a photodiode (1) for receiving the optical signaland for generating a first modulated electrical signal. An amplification circuit (3) receivesthe first electrical signal or a signal related thereto via an n stage (where n is an odd-integer) filter network (2) connected between the photodiode (1) and the amplificationcircuit (3). The output from the amplification circuit is fed to a first equalisation and noisefilter (5). The characteristics of the filter network are such that the total thermal noisepower output of the first noise filter is substantially minimised.
