These demos illustrate the use of fixed-point primitives in the SDF domain. These primitives are used to model hardware implementations with finite precision.

- fixConversion
- Illustration of the different masking options available.
- fixFIR
- Effect of filter tap precision on the frequency response.
- fixIIRdf
- Comparison of a fourth-order direct-form IIR filter implemented with floating-point arithmetic and a similar filter implemented with fixed-point arithmetic.
- fixMpyTest
- Testing of fixed-point multiplication over a range of numbers by comparison against floating-point multiplication. The results should be the same.
