Focus on Noise Cancellation: Two Types

Tx NC
Transmit Noise CancellationReduces the noise when you talk
Rx ANC

Wolfson ANC – What it Does
14 © 2010 Wolfson Microelectronics plc June 2010
1. Caller speech volume through handset speaker
2. Background noise drowns out the handset speaker – you can’t hear the caller
3. Wolfson ANC lowers the background noise so the speech can be heard clearly
1. Handset speaker volume
3. Background noise,ANC ON

• Monitors the incoming signal
• Creates a new signal that is equal in amplitude with the opposite phase
• Mixes the new signal with the incoming signal
