Abstract:
IN A PLUSE DURATION MODULATION DEVICE TRAVELLING DOMAINS ARE NUCLEATED BY THE GUNN EFFECT OR THE LIKE AND THE PATH LENGTHS OF THE DOMAINS ARE VARIED TO VARY THE DURATION OF SIGNAL PULSES DERIVED FROM THE DOMAINS. IN ONE FORM THE DOMAINS ARE NUCLEATED IN RESPONSE TO PERIODIC
TRIGGER PULSES AND THE DURATION MODULATED SIGNAL PULSES ARE UTILISED IN A PULSE PHASE MODULATOR DRIVING A PHASED AERIAL ARRAY.
TRIGGER PULSES AND THE DURATION MODULATED SIGNAL PULSES ARE UTILISED IN A PULSE PHASE MODULATOR DRIVING A PHASED AERIAL ARRAY.
