Telephone headset amplifier with noise blanking capability

摘要

The present invention is directed most particularly to wireless communication systems for interconnection with telephone systems, and more particularly to methods and apparatus to suppress unwanted and annoying audio spikes or bursts that infiltrate the wireless system from ultimately reaching the user's earpiece. An embodiment of the invention is directed to a telephone headset amplifier system with a noise blanking or squelching capability, which attenuates the incoming audio signal when the incoming signal exceeds a predetermined threshold.
