The AD7403 Isolated Sigma-Delta Modulators present on the controller board have a 2 wires signal interface with the FPGA:
The reconstruction of the data provided by the AD7403 modulator can be done using a SINC3 filter. A filter model and HDL implementation are provided in the AD7403 datasheet. Typical filter output characteristics:
The output code resolution and sampling rate can be controlled by changing the filter’s model and decimation. Polyphase interpolation filters are utilized to increase the sampling rate of the system.
