FPRE004 is a technical case study/exercise module focused on the behavior of fixed-point arithmetic in digital signal processing (DSP) and embedded systems. It examines how finite word length (FWL) effects—specifically quantization and rounding—degrade precision when representing real numbers in a fixed-point format.
For a signal uniformly distributed over ([-A, +A]), the signal power ( P_s = A^2/3 ).
Quantization noise power ( P_n = \frac\textLSB^212 ).
Thus:
[
\textSQNR = \fracP_sP_n = \fracA^2/3\textLSB^2/12 = 4 \cdot \fracA^2\textLSB^2
]
In dB:
[
\textSQNR\textdB = 6.02n + 10\log10\left( \frac4A^2(\textrange)^2 \right)
]
For full-scale sine wave ((A = \textrange/2)), this simplifies to ( \approx 6.02n + 1.76) dB.
