(5 pt) Signal x(t) 5cos(2? x5x106x1) Is transmitted. The received signal is 6. 4 cos (2 x 5 x 106 x 1-?) . Assume the phase shift is caused by propagation delay. y(t) a. (3 pt) Suppose [rad]. What is the minimum distance between the transmitter and the receiver? b. (2* pt) Suppose ?--[rad]. What is the minimum distance between the 4 transmitter and the receiver? Page 4 of 9
Please show all steps and show neat work.

4) For the periodic signal below, find the compact trigonometric Fourier series and sketch the amplitude and phase spec ra. If either sine or cosine terms are absent in the Fourier series, explain why -T π /4
1) Find out the amplitude, frequency and phase displacement for given QPSK signal F(t)=100 cos(25t+π/4). 2) For given data incorporate with odd parity and even parity (a) 11011011 (with parity bit) (b) 1 11011011 (without parity bit)
1.On the graph below, make a neat and labeled sketch of the signal s(t) = 2 + cos( t/4 + 1 ),Describe s(t) as odd, even, or neither. What is the energy in s(t)?

Use the frequency-shift rule to find the spectrum of the signal x(t) = s(t) cos(2π(770, 000)t) , where s(t) = 7 − 3 cos(2π(1000)t + π/7). I know the relative "definition" of the frequency shift rule, I am just very confused as to how to apply it.
