IPC: H04M9/00
Filed: 1990-03-28
Abstract: PURPOSE:To prevent howling and singing from being generated by using a transversal type adaptive filter so as to decrease a signal bypassed from two speakers to a microphone. CONSTITUTION:Bypass signals 9a, 9b are A/D-converted by an A/D converter 6a via an amplifier 8 and D/A-converted by a D/A converter 3c and sent to a transmission line 20 via a transmission reception circuit 7. An adaptive filter 5 takes the configuration of a transversal filter and acts like generating a signal minimizing the bypass signal from output signals of A/D converters 6a, 6b, that is, from a speaker 1b to a microphone 9. Thus, the apparent bypass signal to the microphone 9 is almost zero thereby preventing howling and singing from being generated.
