Abstract

UN SISTEMA PARA LA VALIDACION DE MONEDAS COMPRENDE UNA BOBINA TRANSMISORA (2) PARA TRANSMITIR UNA RADIACION ELECTROMAGNETICA DE BAJA FRECUENCIA A TRAVES DE UNA MONEDA (1), Y UNA BOBINA RECEPTORA (3) PARA RECIBIR LA RADIACION QUE HA PASADO A TRAVES DE LA MONEDA. SE PREVE UN AMPLIFICADOR DE INVERSION (4) EN LA VIA DE REALIMENTACION ENTRE LA BOBINA RECEPTORA (3) Y LA BOBINA TRANSMISORA (2), PROPORCIONANDO CON ELLO UN CAMBIO DE FASE DE 180 . ASI, PARA LA UNICA FRECUENCIA QUE CAUSA UN CAMBIO DE FASE DE 180 TACION POSITIVA, Y SUCEDE UNA CONDICION DE RESONANCIA EN ESA FRECUENCIA. LA MONEDA SE PUEDE VALIDAR MIDIENDO LA FRECUENCIA DE ESTA RESONANCIA Y COMPARANDOLA CON UN VALOR DE REFERENCIA.
