FixPt Sign
Indicate the sign of the input.
Description
The FixPt Sign block is a masked S-function that indicates the sign of the input.
The output is a signed data type with the same number of bits as the input, and with nominal scaling (a slope of one and a bias of zero):
- The output is 1 when the input is greater than zero.
- The output is 0 when the input is equal to zero.
- The output is -1 when the input is less than zero.
