2. Matlab Simulations (a) Generate 1,000,000 samples of white Gaussian noise of unit variance. The sampling is set as 1 sample/second. Use this as the in-phase. Plot a segment of it over time. Repeat the above for the quadrature. Plot the noise envelope over a segment of time. (b) Consider that you are making a decision every sample, and no signal (target) is present. For the probability of false alarm to 10^-3, what is the false alarm time. The signal bandwidth is the sampling rate

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79
