Straight binary; one
polarity with true input
code, true zero output.
Complementary binary;
one polarity with
complementary input
code, true zero output.
Straight offset binary;
offset half-scale,
symmetrical about zero,
no true zero output.
1’s complement; offset
half-scale, symmetrical
about zero, no true zero
output, MSB complemented
(need inverter at B1).
Offset binary; offset half-
scale, true zero output.
2’s complement; offset
half-scale, true zero
output, MSB complemented
(need inverter at B1).
