Transducer Hardware Overview
Transducer Types
All transducers that can connect to the fetal sensor sockets can be used.
Functional Description of the Transducer CPU
The CPU section of the transducers is made up of the following main functional blocks:
•
CPU (micro controller)
•
Analog-to-Digital Converter
•
Communication Transceiver (CAN bus driver)
•
EEPROM
CPU (Micro Controller)
A single-chip processor is used to control the transducer, generate the front-end control signals,
control the analog-to-digital signal conversion, and to perform the signal processing.
Analog-to-Digital Converter
Analog-to-digital (A/D) signal conversion is carried out by the 16-bit AD converter. Digital signals are
directly communicated from the A/D converter to the CPU.
