Disk storage channel. Binary data storage with a thin-film disk can be approximated by an input-dependent additive white Gaussia
n 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
