Question 2 (25 marks) - Transformation of a Random Variable A class-B transistor amplifier with a volage gain of two has cross-over distortion, resulting in a non-linear function from input x to output y(x) as plotted below. y(x) slope=2 /slope=2 A zero-mean Gaussian random process with a standard deviation of 1 is fed into the input. i.e. X~ N(0, 1²). a) Draw an illustration of the mapping from px (x) into py(y) through the above non-linear function. (5 marks) b) Determine the output PDF py(y) and write as a mathematical expression. (15 marks) c) Plot the py(y). (5 marks) -0.5, 0 0.5
