1. Consider the signal set in Figure 1 for binary data transmission over a channel disturbed by AWGN. The noise is zero-mean and has two-sided PSD No/2. As usual, si(t) is used for the transmission of bit "0" and s2(t) is for the transmission of bit 1." Furthermore, the two bits are equiprobable.

T = 4V The figure shows a pendulum with length L that makes a maximum angle @o with the vertical. Using Newton's Second Law, it can be shown that the period T (the time for one complete swing) is given by -TT/2 dx L go 1 - k2 sin2(x) where k = sin(100) and g is the acceleration due to gravity. If L = 2 m and 60 = 46°, use Simpson's Rule with n = 10 to find the...
Problem 31: (34 points) 1. (10 points) A pulse width modulated (PWM) signal fPwM(t) in Figure 2. The symbol D represents a duty cycle, a number between zero and one. Determine the compact trigonometric Fourier series coefficients (Co C,11 %) of the signal f(t). 2. (10 points) One use of PWM is to generate variable DC voltages. While the PWM signal is not DC, you should be able to see from your results in part 1 that it hss a...
