ANS:A SENSOR IS A ASSEMBLY REQIRED TO DETECT AND COMMUNICATE A PARTICULAR EVENT WHILE A TRANSDUCER IS THE ELEMENT WITHIN THE ASSEMBLY WHICH ACCOMPLISHES ONLY THE DETECTION OF THE EVENT. |
HOW WE CONVERT SIGNED DECIMAL INTO HEX AND BINARY? |
ANS:WE HAVE DECIMAL "-32".ACCORDING TO NORMAL /UNSIGNED CONDITION RESULT WILL BE "00100000".BUT WHEN WE USE SIGNED DECIMAL WE TAKE COMPLEMENT OF "00100000" WHICH IS "11011111" AND THEN WE ADD "1" IN THIS RESULT.NOW WE GET RESULT OF UNSIGNED DECIMAL. FIRST STEP:BCD OF 32. SECOND STEP:CHANGE BIT "0" INTO "1" AND "1" INTO "0". THIRD STEP:ADD "1" IN RESULT OF 2ND STEP. FOURTH STEP:NOW YOU HAVE RESULT. 1.00100000 2.11011111 3.11011111+1=11100000 4.RESULT=E0H |
