In Q15 format a 16-bit signed value represents numbers in the range
Answer: D
Correct answer: \( -1 \) to just under \( +1 \)
Q15 places the binary point immediately below the sign bit, so the 16-bit integer is read as a fraction: the range runs from \( -1 \) to \( 1 - 2^{-15} \). The format is used where fractional arithmetic is needed on a processor with no floating point unit.
