. A 200mV rms value sinusoidal signal is applied to and ideal 12 bits ADC. The full range peak-to-peak voltage of the ADC is 1.2V. a. Find the SNR of the ADC output. b. Now the input sinusoidal is full range but comes with an additive Gaussian noise with standard deviation of 0.5 V. What is the SNR of the input signal

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

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

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.
