{f_{carrier}} \normalsize < \tau < \Large \frac{1}{f_{data}}$ The carrier frequency is still 134.4kHz but we need to determine the data signal frequency. According to the FDX-B protocol, the ...

#define FDX_B_ENCODED_BYTE_SIZE (((FDX_B_ENCODED_BIT_SIZE) / 8)) #define FDX_B_PREAMBLE_BIT_SIZE (11) #define FDX_B_PREAMBLE_BYTE_SIZE (2) #define FDX_B_ENCODED_BYTE ...

So I have to assume it just garbage. Still I'm curious why 19 bytes. Anyway, I read somewhere that this transponder uses FDX-B, so the first question is whether TMS3705 supports FDX? Assuming it is ...
