Experiment 5. Signal sampling and sampling theorem matlab. hhitit 14 1. According to sampling theorem, Realize the sample signal fs(t) and spectrum Sa(t) after impulse sampling by matlab, and use fs(t) Sa(t), to calculate the error between the reconstructed signal and the original to construct raised cosine signal - 2. Realize the rising cosine signal with sampling theorem by matlabu www f(0) = (1 + cos 4). 16151 Which e = 1, 1 = r; to get sampling signal fs(t) and spectrum after impulse sampling, Use f(t) to construct the rising cosine signal, to calculate the error between the reconstructed signal and the original raised cosine signal -

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

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.
