Abstract
In this paper, an acoustic filter with low frequency bandstop and a broadband (0.3–3 kHz) bandstop filter are presented. In this paper, control algorithm and related equipment are integrated with piezoelectric ceramic thin film, ADC and FPGA to study a system which can mix acoustically in the process of acoustic transmission and only allow one-way transmission of sound waves.
