- Simulating CIC filtering/decimation without the Filter Design Toolbox
- License: Freeware

Recently needed to see the effects of a CIC decimating filter but realized that with my new license of Matlab, I did not have access to the Filter Design Toolbox. This is a quick attempt at a simulation to re-create the effects of CIC-decimation but without the fixed-point access to the multi-rate filter design tool..

- Windows Server 2003 Active Directory Design and Implementation
- License: Shareware

Written by an experienced Active Directory designer and implementor, this book walks you through the concepts of the Active Directory, and the Active Directory design issues associated with various business environments, outlining strategies, principles and best-practice for creating the design, before leading you through the implementation step-by-step. A well thought-out Active Directory provides a solid foundation for other services which will lower support costs and allow companies to centrally manage their environment.

- Durrani-Chapman Optimal All-Pole Lowpass Filter Design
- License: Freeware

The code was generated according to T.S. Durrani, and R. Chapman. Optimal All-Pole Filter Design Based on Discrete Prolate Spheroidal Sequences. IEEE Transactions on Acoustics, Speech and Signal processing, Vol ASSP-32, No.4, August 1984. This filter design uses discrete prolate spheroidal sequences (Slepian sequences) to optimize the magnitude response function in the passband under a quadratic constraint. Slepians are unique in their ability to concentrate power in a specified bandwidth. This filter is all-pole, near-linear in phase (which is why it should be forward/backward filtered on implementation if nonlinear phase shift is not acceptable.

- FIR Designer
- License: Shareware

FIR Designer is an interactive software tool for Finite Impulse Response (FIR) filter design. It has a very intuitive user interface that gives the possibility to see in real time the effects of changing various filter parameters and supports the following filter shapes: low-pass, low-pass square root raised cosine, high-pass, band-pass, band-stop, Hilbert transform, averaging, differentiator and CIC-like for decimation. Some of the filter shapes can be combined with one of the following window functions: rectangular, triangular (Bartlett), cosine, Hamming, Blackman (with ?=0.

- Farrow Resampler
- License: Shareware

These three files include Farrow filter design and implementation. One is float and second is fixed point. One can find the theory of the Farrow resampler in the literature. Here there is an example of Matlab implementation. The design use symmetric and antisymmetric filter thus saving 1/2 of the multipliers. Note that the filter design includes "firls" (Signal Processing Toolbox) but one can replace the function with any other design method..

- Frequency-Domain Min-Max Optimizationfor Delta-Sigma Modulators
- License: Shareware

Matlab codes are provided for min-max optimization for loop-filter design in delta-sigma modulators. The MATLAB codes are based on our recent paper: M. Nagahara and Y. Yamamoto, Frequency-Domain Min-Max Optimization of Noise-Shaping Delta-Sigma Modulators, to appear in IEEE Trans. SP, 2012. A draft can be down-loaded via: http://www-ics.acs.i.kyoto-u.ac.jp/~nagahara/ds/manuscript.pdf We give two matlab codes: [ntf,R]=NTF_MINMAX(order,OSR,Hinf,f0,zf) [ntf,R]=NTF_MINMAX_MB(order,OSR,Hinf,f,zf) By these codes, one can obtain lowpass/bandpass (by NTF_MINMAX) and multi-band (by NTF_MINMAX_MB) filters for noise-shaping delta-sigma modulators that minimize the maximum magnitude of the noise transfer function (NTF) in fixed frequency band(s).
