Abstract :
The phase response of a dispersive interdigital delay line is shown to be affected by dispersion of the surface wave. A device with a time¿bandwidth product of 850 and a nonlinear group-delay characteristic gave results consistent with dispersion due to mass loading and topographic effects.
