Typical FAA Installation:
The DSP-8200d is useful in many FAA applications. Each module can be configured for
tone suppression or broadband noise reduction.
Tone suppression prevents loud signaling tones from reaching air traffic controllers and
eliminates or reduces naturally occurring heterodynes between air traffic control and
multiple airplanes.
Noise reduction is useful in applications where channel signal to noise is poor and may
be used to enhance intelligibility and reduce listener fatigue.
The DSP-8200d is installed prior to controller switching equipment in the receive audio
chain and does not require any FAA equipment modification.
Application sites may include FAA Control Centers, Automatic Flight Service Stations,
TRACONs, Control Towers, and Flight Service Stations.
