Hi,
Does anyone know how to compute the lower parity of the A10202 format? This is a 37 bit format with a 12 Bit FC and 19 Bit ID.
The upper parity is ODD and is computed with the following formula:
x(2) & x(3) & x(5) & x(6) & x(8) & x(9) & x(11) & x(12) & x(14) & x(15) & x(17) & x(18) & x(20) & x(21) & x(23) & x(24) & x(26) & x(27) & x(29) & x(30) & x(32) & x(33) & x(35)
where X is a bit in the entire card output
X(0) is the position of the upper parity (bit 1)
X(36) is the position of the lower parity (bit 37)
Not sure how to calculate X(36)
Here are some examples of card outputs:
