  • Differential demodulators using surface elastic wave devices
    Patent number: 4054841
    Abstract: A differential demodulator of phase-modulated digital data trains includes a device, for example a piezoelectric substrate, which transmits acoustic surface waves and includes comb-shaped input and output transducers on the substrate. The delay in the transmission of acoustic surface waves between the input and output transducers is used in the process of demodulating the phase modulated digital data trains.
