Abstract
Se proporciona una disposicion de bucle enganchado en fase inalámbrico distribuido para sincronizar la forma de onda de modulacion de la portadora de transmision, tal como la cronizacion de pulso transmisor en una disposicion de VEA pulsada y la funcion de barrido de transmision para sincronizacion de radio frecuencia barrida. Para eliminar el efecto de ruido de fase en la senal de la línea de alimentacion eléctrica se utiliza un bucle enganchado en fase para filtrar esta senal. La salida filtrada se utiliza como una referencia para un segundo bucle enganchado en fase vinculado a un oscilador controlado para proporcionar un algoritmo de bucle enganchado en fase distribuido que es inalámbrico y sincroniza automáticamente las disposiciones de VEA adyacentes.
