Name: Fixed-Point Quantization
ID: m11921
Language: English (en)
Summary: Finite word lengths introduce quantization error in fixed-point systems. Truncation quantization causes a larger maximum error and a negative bias compared to rounding, but is easier to implement in hardware. Similarly, wraparound overflow is typically worse than saturation, but also requires more hardware.
Subject: Science and Technology
Keywords: overflow, quantization error, rounding, roundoff error, saturation, truncation, truncation error, wraparound error
