| Abstract(in English) | Currently, DTMF is used in the phone dialing system. It presents in the frequency band audio signal. So the automatic response system, such as voicemail or telephone banking malfunction occurs when the voice signal is mistaken as the DTMF signal. Therefore, the architecture proposed in this study, band elimination filters are implemented in the FPGA to efficiently remove the DTMF signals from the speech signal, can be used to prevent malfunction. |
