Represent numbers as integers or fractions with a fixed decimal place. They are highly cost-effective, consume less power, and feature simpler hardware layouts. However, they require careful programming to prevent register overflow or precision loss.
Why use a 16-bit fixed-point DSP for a hearing aid but a 32-bit floating-point DSP for radar? The book uses dynamic range and signal-to-noise ratio (SNR) equations to explain this trade-off clearly.
