- 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..

- 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.

- Digital Resistor-Capacitor (RC) Filter
- License: Freeware

Returns equivalent IIR coefficients for an analog RC filter Usage: [B,A] = RC_FILTER(r, c, fs, type); R is the resistance value (in ohms) C is the capacitance value (in farrads) FS is the digital sample rate (in Hz) type is a character string defining filter type Choices are: 'high' or 'low' This function uses a pre-calculated equation for both of these circuits that only requires the resistance and capacitance value to get a true digital filter equivalent to a basic analog filter. The math behind these equations is based off the basic bilinear transform technique that can be found in many DSP textbooks.

IT is a C library of mathematical, signal processing, speech processing, and communications classes and functions. It is being developed by researchers in these areas and is widely used by researchers, both in the communications industry and universities. The kernel of the IT library are templated vector and matrix classes, and lots of functions for vectors and matrices. Such a kernel makes IT library similar to Matlab . Features: - templated vector and matrix classes - sparse vector and matrix classes - elementary functions on vectors and matrices - matrix decompositions such as eigenvalue, Cholesky, LU, Schur, SVD, and QR - solving linear system of equations (including over- and underdetermined) - random number generation (Mersenne Twister generator) - binary and Galois types (scalar, vector and matrix) - integration of...
