11.3 Derive the expression for the minimum detectable power using a photocon- ductor in the video mode (that is, no local-oscillator power) and assuming that the main noise contribution is the generation-recombination noise. The optical field is given by e(t) = E(1 + cos wmt) cos oot, and the signal is taken as the component of the photocurrent at @m. stor with character-
