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.
What is the function of gate signal in 8254 timer? The 8254 has three independent 16-bit counters, which can be programmed to. Work in any one of possible six modes. Every cou
