Abstract
CIRCUITO ELECTRICO PARA UN DISPOSTIVO DE SEGUIMIENTO DE UNA PISTA DESEDA EN UN PORTADOR CON PISTAS DE INFORMACION ADYACENTES. LAS SEÑALES DE DETECCION (HF) Y DE CONTROL (RE) QUE SALEN DEL DISPOSITIVO DE SEGUIMIENTO, SE INTRODUCEN EN EL CIRCUITO QUE ESTA FORMADO POR UN DETECTOR (11); UN DISPOSITIVO DE UMBRAL (12) QUE GENERA UNA SEÑAL DE ONDA CUADRADA; UN AMPLIFICADOR (14); UN CONMUTADOR DE UMBRAL (16); UN BIESTABLE (30) QUE DISPARA POR LA SALIDA DEL DISPOSITIVO DE UMBRAL, Y UNA SERIE DE PUERTAS LOGICAS (13,17,18 Y 19). LA SEÑAL QUE GENERA EL CIRCUITO SE APLICA AL MOTOR DE POSICIONAMIENTO DEL DISPOSITIVO DE SEGUIMIENTO.
