Studies using surface acoustic waves (SAWs) have typically employed SAWs with sinusoidal waveforms. Recently, a technique to generate a single cycle SAW pulse by compressing SAWs in a wide-frequency range using a chirp interdigital transducer (chirp-IDT) has been developed. In this study, we employed this SAW pulse to investigate the ef-fect of electromagnetic crosstalk generated during SAW generation on the quantization of the acoustoelectric current flowing through a one-dimensional channel.
