Generation of audio test signals with matlab implementation

The following Matlab project contains the source code and Matlab examples used for generation of audio test signals with matlab implementation. The present submission is a set of seven Matlab functions that provides a generation of wave packets of: 1) Sine wave signal 2) Square wave signal 3) Chirp signal 4) Pink noise signal 5) White noise signal 6) Sinc wave signal (sin(x)/x) (as odd or even function) Each function passes the generated signal to the analog output of the sound card so one can use it for acoustic, audio or other measurements.

Uniform quantization in matlab

The following Matlab project contains the source code and Matlab examples used for uniform quantization. This MATLAB exercise illustrates the process of uniform quantization of a speech sample using a range of B-bits per sample, and displays the unquantized signal, the quantized signal and the error signal at the selected bit rate along with plots of signal and error power density spectrum, and the histogram of the quantization error signal.

This zip file contains functions related to apodization and symmetric window generation: 1) atomwin - Window based on atomic functions 2) barthewin - Barcilon-Temes window 3) conneswin - Connes window 4) coshwin - Hyperbolic cosine window 5) coswin - Minimum sidelobe cosine window 6) dchebwin - Dolph-Chebyshev window 7) denkwin - Denk window 8) dslepwin - Discrete Prolate Spheroidal Sequences (DPSS) window

Simulation engine for hybrid continuous- and discrete-time systems in matlab

The following Matlab project contains the source code and Matlab examples used for simulation engine for hybrid continuous- and discrete-time systems . The odehybrid library makes it easy to create simulations of dynamical systems with both continuous-time components (such as physical models) and multiple discrete-time components (such as digital controllers and signal processors).

Resampling of an image with a polar sampling pattern using the built-in 'improfile' function in matlab

The following Matlab project contains the source code and Matlab examples used for resampling of an image with a polar sampling pattern using the built-in 'improfile' function . This function uses the built-in 'improfile' function to resample an image with a polar coordinate system.

Equalizer effects in matlab

The following Matlab project contains the source code and Matlab examples used for equalizer effects. Here by using the 10 band equalizer we have implemented various effects such as Bass, Treble, Booster, Jazz, Classical, Rock, Powerful, Soft, Dance, Pop, Vocal by the use of FDA tool / IIR FILTER Guided by.

Digital resistor capacitor (rc) filter in matlab

The following Matlab project contains the source code and Matlab examples used for digital resistor capacitor (rc) filter. 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'
