Disk storage channel. Binary data storage with a thin-film disk can be approximated by an input-dependent additive white Gaussian noise channel where the noise n has a variance dependent on the transmitted (stored) input. The noise has the following input dependent density: 2 2ơ 2To2 2ơ 2Ta2 0 and σ-31ơ1. The channel inputs are equally-likely. a. For either input, the output can take on any real value. On the same graph, plot the two possible output probability density functions (pdf's). i.e. Plot the output pdf for 0 and the output pdf for x -1. Indicate (qualitatively) the decision regions on your graph. 2 72 2πσ 2 2πσ 2 0

Since 1 km = 1.057×10^-13 light years then the correct answer would be  the light from star 2 reaches star 1 in 63 years. this would be the conclusion about the stars if  star 3 is 138 light years away from star 1 and 75 light years away from star 2.  you for posting your question. i hope that this answer you. let me know if you need more .
