ACOUSTOELECTRONIC ANALOG STORAGE DEVICE Russian patent published in 1995 - IPC

FIELD: radio electronics. SUBSTANCE: radio pulse coming from generator 14 is converted into surface acoustic wave by means of electroacoustic transducer 3 and stored on working surface 2 of sound conductor in the form of homogeneous stationary sinusoidal reference potential pattern between surface acoustic wave transducers 3 and 4 as a result of short-time electronic pulse irradiation by first gun 6. Input signal of device modulates electron beam of second gun 11 affording scanning along reference pattern. Reference pattern is subjected to spatial amplitude modulation. Repeated pulse irradiation by first gun 6 results in generation of surface acoustic wave that carries stored input signal in the form of amplitude modulation. Stored signal length depends on time of second-gun beam scanning over working surface of sound conductor 1. EFFECT: increased stored signal length. 2 dwg
