Description

전자 박자계Electronic time signature

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명에 따른 박자 계의 전체 회로도.1 is an overall circuit diagram of a time signature system according to the present invention.

Claims (3)

소정의 기준 주파수를 발생시키기 위한 주파수 발진부와; 마이크로폰을 통해 입력된 아날로그 신호를 증폭하고, 이를 정형하여 디지틀 신호로 변환 시키기 위한 카운터 입력부와; 박자계의 속도를 설정하기 위한 스위치부와; 상기 카운터 입력을 계수하며 스위치 입력에 따른 표시출력을 연산하기 위한 연산부와; 상기 스위치에 의한 박자계의 설정시 소정의 숫자를 표시하기 위 LCD 표시부 및; 박자계의 출력을 외부로 표시하기 일한 박자계음 출력부로 구성시켜서 됨을 특징으로 하는 전자 박자계.A frequency oscillator for generating a predetermined reference frequency; A counter input unit for amplifying the analog signal input through the microphone, shaping the analog signal, and converting the analog signal into a digital signal; A switch unit for setting the speed of the magnetic field meter; An operation unit for counting the counter input and calculating a display output according to a switch input; An LCD display unit for displaying a predetermined number when setting the time signature by the switch; Electronic time meter, characterized in that the output of the time meter is composed of a time meter output unit. 제1항에 있어서, 상기의 박자계음 출력부는 박자계의 출력 신호를 가청음으로써 외부로 출력하는 가청음 출력부 또는 외부음과의 혼신을 피하기 위해 박자계의 출력신호를 시각적으로만 표시하기 위한 시각적 출력부를 포함함을 특징으로 하는 전자 박자계.The visual output of claim 1, wherein the time signature sound output unit only visually displays an output signal of the time signature to avoid interference with an audible sound output unit or external sound which is output to the outside as an audible sound. Electronic time signature, characterized in that it comprises a wealth. 제1항, 또는 제2항에 있어서, 상기의 전자 박자계는 박자계 외출력신호를 가청음 또는 시각적 출력으로 선택하기 위한 선택 스위치를 포함함을 특징으로 하는 전자 박자계.The electronic time signature according to claim 1 or 2, wherein the electronic time signature includes a selection switch for selecting an external time signature signal as an audible sound or a visual output. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
