3. A lossy medium is with a refractive index n=1.5+0.0015*i. If the initial power intensity of a plane wave
at the wavelength of 1.5 um is lin and the power intensity of the plane wave after propagating 1 mm
inside the lossy medium is lout, then the optical loss is given by Lo=10 log1,(/out/lin) in dB scale. Please
determine the loss value of Lo. (Note that log 1, e = 0.4343)

6. We have a signal x(n) = xa(t)]1=nT; t=nT1 where T1 7 msec, and we wish to convert x(n) to y(m) such that y(m) = xa(t)]t=mT2 with T, = 5 msec. Develop a system to do this, being sure to specify the frequency re- sponse of any filters that are used (ideal responses are okay). Are there any restrictions on xa(t) that should be imposed so that this is possible?
In the process of performing an analysis, you determine that you need to improve the precision by limiting the error in the absorbance to 9.400 x 10%. You attempt to achieve this by reducing the amount of stray light that reaches the detector. What is the maximum amount of stray light that can reach the detector that will limit the error in the absorbance to 9.400 x 10 for a true absorbance of 1.0000000? s= 222 x10-5 Incorrect
