V4 HW Discussion

From RFID Wiki


[edit] About the schematic

Above one can see the schematic for RFID Guardian HW V4. It's a start, to discuss about how the hardware should look like. It's by no means final, every bit is open for discussion. So please, do feel free to tell which parts should be changed and which should be kept or which should be added.

It's good to define (also still open for discussion) a few global blocks:


[edit] Global blocks

/A/ Computer and communication between V4 hardware and software

-Discuss which software should be on the computer and how communication between Guardian and PC should take place

-In the above schematic Block 1 & 2

/B/ Digital Signal Processing Block (DSPB)

-Discuss which parts should be used to do the digital signal processing (FPGA VS ARM etc.)

-In the above schematic Block 3 & 4

/C/ Sampeling: ADC and DAC

-Discuss which ADC and DAC should be used, what do we need how are we going to implement things

-In the above schematic Block 5 & 6

/D/ Analog Signal Processing Block (ASPB)

-Discuss about which frontends and HF amplifiers should be used

-In the above schematic Block 7/8/9/10 & 11

/E/ Power supply

-Discuss about which power supply should be used (e.g. battery VS wall socket adapter)

-In the above schematic Block 12


We could also make the antenna a separate block if any one feels the urge to...
