A bipolar PWM full bridge circuit has a VAN and VBN of 175V and 125V respectively. It also has a Vd that is 4 times Vo. What is Vo? What is Vd? What are the duty cycles D1 and D2? Then calculate the Vr.rms at D1. Now calculate vr.rms at each duty cycle D1 from 0 to 1, with 0.1 steps in between. When is Vr.rms minimal and maximum based on terms of D1?

A game of chance is played on a wheel that contains 34 numbers (16 are red, 16 are black, and 2 are green). When the wheel is spun, the ball is equally likely to land on any of the 34 numbers. Suppose that you bet $7 on red. If the ball lands on a red number, you win $7; otherwise you lose your $7. Let X be the amount you win on your $7 bet. Then X is the random variable whose probability distribution is as follows. a. Find the expected value of the random variable X. The expected value is (Round to three decimal places as needed.) X P(X = x) 7 0.471 -7 0.529 Use this to complete parts (a) through (d) to the right.
