Frequency Domain System Identification Toolbox for MATLAB
The FdIdent toolbox provides tools for frequency domain model identification and validation. A user-friendly GUI is also available to guide the user through the system identification steps:
- Design of optimized periodic excitation signals (multisine, binary, three-level) and optimized Discrete Interval Binary Signals (DIBS) signal generation.
- Identification of continuous-time or discrete-time systems with unknown delay.
- Model order selection.
- Model validation, including simulation, calculation of residuals, and test of cost functions.
- Calculation of confidence intervals of amplitude/phase and poles/zeros.
- Model conversion to and from the Control System Toolbox and System Identification Toolbox objects.
Frequency domain methods support continuous-time modeling, which can be a powerful and highly accurate complement to the more commonly used discrete-time methods. The methods in the toolbox can be applied to problems such as the modeling of electronic, mechanical, and acoustical systems.
MP Toolbox: Multiple precision toolbox for MATLAB

The MP toolbox provides an object-oriented solution for easy and user-friendly simulation of floating point arithmetic and calculations with arbitrary precision.
Textbook on Quantization noise and solution manual
The book summarizes the theory of quantization. The theory is developed for uniform quantizers and floating-point number representation. Applications to roundoff in FIR/IIR filters, feedback control systems, and numerical calculations are discussed. A solutions manual is available, containing solutions to exercises given after each chapter
