디지털 신호: 두 판 사이의 차이

'''디지털 신호'''({{llang|en|digital signal}}, {{문화어|수자신호}})는 데이터를 일련의 [[이산 공간|이산]] 값들로 표현하기 위해 사용되는 [[신호]]로서, 무한한 단계들의 비연속적인 파형으로 정의할 수 있다.<ref>{{서적 인용|url=https://books.google.com/books?id=1eO7kLWUmYIC&lpg=PA49&ots=EBhxEwk7bY&dq=digital%20signal%20logic&pg=PA4#v=onepage&q=digital%20signal%20logic&f=false |title=Digital Design with CPLD Applications and VHDL |author=Robert K.
