General Description

Most modern speakerphones use half-duplex operation, which alternates transmission between the far-end talker and the speakerphone user. This is done to ensure stability because the acoustic coupling between the speaker and microphone is much higher in speaker phones than in handsets where the coupling is mechanically suppressed.
