Explain Noise
Noise is unwanted signals which degrade the desired signal content and therefore the performance of the system. Noise might be produced either externally or internally to the system. External noise contains atmospheric interference, man-made interference, lightning, etc. Internal noises are produced by the components and devices used in the system.
A copper cylinder 40 cm diameter and 10 mm thick is nearly wound with a layer of 4mm diameter steel wire under a tensile stress of 80 Mpa. If the steam under a pressure of 5 Mpa is
