Functional Description
2.1
Analog Front End (AFE) Description
The Analog Front End section of the ARCOFI is the interface between the analog
transducers and the digital signal processor. In the transmit direction, the AFE-function
is to amplify the transducer input signals (microphones) and to convert them into digital
signals. In the AFE-receive section, the incoming digital signal is converted to an analog
signal which is output to an earpiece and/or a loudspeaker.
A block diagram of the AFE is shown in figure 15.
