What is Modulation and Demodulation ? Need of Modulation.

-




Modulation of a radio wave can be performed by varying one or more of its signal components—amplitude, frequency, or phase—while keeping its other signal components constant. (Pulse modulation is yet another form of modulation, without a carrier, in which pulses with precisely known characteristics are transmitted and details can be learned about a target by receiving the reflected pulses from the target.)

Ash handling refers to the method of collection, conveying, interim storage and load out of various types of ash residue left over from solid fuel combustion processes. The most common types of ash resulting from the combustion of coal, wood and other solid fuels. bottom ash bed ash fly ash ash clinkers Ash handling systems may employ different forms of pneumatic ash conveying or mechanical ash conveyors. A typical ash handling system may employ vacuum pneumatic ash collection with ash conveying from several ash pick up stations and resulting in delivery to an ash storage silo for interim holding prior to load out for disposal or reuse. Pressurized pneumatic ash conveying may also be employed. Coarse ash material such as bottom ash is most often crushed in clinker grinders (crushers) prior to being transported in the ash conveyor system. Very finely sized fly ash often accounts for the major portion of the material conveyed in an ash handling system. It is collected from baghouse type ...

Working Of 4 Stroke Petrol/Spark Ignition Engine. || Hindi || Jignesh Shah

-
Image
  four-stroke  (also  four-cycle )  engine  is an  internal combustion  (IC) engine in which the  piston  completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: Intake : Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. Compression : This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (bel...
