Speakerphone Implementation
About this Application Note
The intention of this application note is to give a thorough understanding of the
speakerphone implementation of the ARCOFI-SP. After introducing the general aspects
of speakerphones and the related problems (chapter 1) the ARCOFI-SP and all its
parameters are described (chapter 2). In chapter 3 practical aspects are discussed and
an example set of coefficients is given.
In the application note, the term "telephone" is used to describe the particular hardware,
the ARCOFI-SP is used for. Nevertheless, the ARCOFI-SP fits to a variety of
applications, like intercoms, videoconferencing systems etc.
Throughout this application note, registers or CRAM coefficients are written in bold and
capital letters (See “Notation and Coefficients” on page 138).
Some ARCOFI-SP parameters are related to the maximum PCM value. In the
application note A-law coding is assumed, therefore this value is written as 3.14 dBm0.
For -law coding 3.17 dBm0 would be correct.
