Name = Ishika Gupta... ~!! ANALOG AND DIGITAL SIGNALS !!~ Difference Between Analog And Digital Signal Analog and digital signals are the types of signals carrying information. The major difference between both signals is that the analog signals that have continuous electrical signals, while digital signals have non-continuous electrical signals. ● ANALOG SIGNALS The analog signals were used in many systems to produce signals to carry information.  These signals are continuous in both values and time. The use of analog signals has been declined with the arrival of digital signals. In short, to understand the analog signals –  all signals that are natural or come naturally are analog signals. ● DIGITAL SIGNALS Unlike analog signals, digital signals are not continuous, but signals are discrete in value and time. These signals are represented by binary numbers and consist of different voltage values. ● Difference Between Analog and Digital Signal... We know that the major differ...

 ■ INGESTION = the human beings have a special organ for the ingestion of food. It is called mouth. ■ DIGESTION = the mouth cavity or buccal cavity contains teeth , salivary gland ,and tongue. 10 feat cut the food into smaller pieces , chew and grind it. The celebrity gland in our mouth produce saliva. Our tongue helps in mixing The Saliva with food. The salivary gland helps in chemical digestion by secret enzymes. That is salivary amylase which is digest the starch present in food into sugar. The slightly digested food in the mouth is swallowed bite the tongue and goes down the food pipe called Oesophagus , when the slightly digested food enters the food pipe ,the walls of food pipe start contraction and expansion movement that is called Peristalic movement. The food is further digested in the stomach. It is Churned in the stomach for about three hours. During this time , the food breaks down into still smaller pieces and forms a semi solid state. The stomach wall contains three t...
