Abstract

EN UNA DISPOSICION DE CIRCUITO PARA LA GENERACION DE UNA SEÑAL DE PARADA PARA UN DESARROLLO DE BUSQUEDA DE EMISOR EN UN RECEPTOR DE RADIO, EN DONDE SE DEMODULA UNA SEÑAL RECIBIDA Y ADEMAS SE DERIVA UNA SEÑAL DEPENDIENTE DE LA INTENSIDAD DE CAMPO RESPECTIVA, SE FORMA LA PROPORCION DE TENSION DE LA SEÑAL DEMODULADA. UNA SEÑAL DE PARADA SE GENERA CUANDO LA PROPORCION DE TENSION CONTINUA PERMANECE BAJO UN VALOR DADO PREVIAMENTE Y LA INTENSIDAD DE CAMPO SOBRE UN VALOR DADO CON ANTERIORIDAD.
