X(t) denotes a zero-mean wss gaussian random process with autocorrelation function rx(t)-4sinc2(10%) 1. what is the power in this process? 2. determine the power spectral density, sx(f), for this process. 3. what is the bandwidth of this process? 4. assuming that this process passes through an ideal lowpass filter with a band- width of 5 khz and the output is denoted by y(t), determine sy(f), the power spectral density of y(t), and the total power in the output process. 5. determine the pdf of random variables x (0), x (10-4), and x (1.5 x 10-4). 6. show that random variables x (0) and x(10-4) are independent but x(0) and x(1.5 x 10-4) are dependent.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
