ClearSpeech Adaptive Speech Filter
The ClearSpeech Adaptive Speech Filter is an algorithm designed
to filter noise from audio signals containing both speech and noise.
It is implemented in a circuit board containing DSP circuitry and a
small audio power amplifier.
Immunity from RF Interference
CLRspkr contains circuitry to reduce interference from the
transmitted radio signal. There are filters on all input wires, and
decoupling capacitors at key points throughout the electronics.
There is a ferrite inductor in series with the positive power lead.
Audio input is via a coupling transformer. The audio input ground is
not connected to the power return. This helps reduce any ground
loops.
