Abstract

REPRODUCTOR DE SEÑALES REGISTRADAS EN CINTA MAGNETICA. INCLUYE UN TRANSDUCTOR CON UNA CABEZA REPRODUCTORA Y UN DISCRIMINADOR DE AMPLITUD. ESTE DISCRIMINADOR RECIBE UNA SEÑAL PROPORCIONAL A LA SEÑAL DE ACCIONAMIENTO DEL TRANSDUCTOR, Y QUE TIENE DOS VALORES DE UMBRAL CON EL FIN DE DESVIAR AL TRANSDUCTOR A SUS DOS POSICIONES EXTREMAS. CUANDO SE REBASA UNO DE ESTOS VALORES, EL DISCRIMINADOR SUMINISTRA UNA SEÑAL DE CONMUTACION QUE CONTROLA A UN GENERADOR DE IMPULSOS, QUE A SU VEZ PRODUCE SEÑALES DE SELECCION DE PISTAS.
