In the feedback system shown below, the noise component of output is given by (assume high loop gain at frequencies of interest):
(a) \(\frac{-\mathrm{N}(s)}{\mathrm{H}_{1}(s)}\)
(b) \(\frac{\mathrm{N}(s)}{\mathrm{H}_{1}(s)}\)
(c) \(\frac{\mathrm{N}(s)}{\mathrm{H}_{1}(s) \mathrm{H}_{2}(s)}\)
(d) \(\frac{-\mathrm{N}(s)}{\mathrm{H}_{1}(s) \mathrm{H}_{2}(s)}\)
