What are various Pipeline Hazards. Explain each hazard with some common solutions that arebeing employed today?

A continuous signal contains the following two components:
x1(t) = 3 cos 20πt
x2(t) = 3 cos 50πt
(a) Find the minimum required sampling rate to avoid aliasing.
(b) Draw the discrete time signals obtained after sampling, when sampled with Fs = 100 Hz. Explain the disadvantage(s), if any, of sampling beyond the Nyquist rate.
(c) Assume the sampling rate is Fs= 40 Hz, which components are exposed to aliasing effects? Support your answer by showing “Nyquist intervals” and the aliased frequencies.

A low voltage digital device has a low state of 0 V and a high state of

The resistance of a starter for a 200-V, shunt motor is such that maximum starting current is 30 A. When the current has decreased to 24 A, the starter arm is moved from the first to the second stud. Calculate the resistance between these two studs if the maximum current in the second stud is 34 A. The armature resistance of the motor is 0.4 Ω.
