DSP System Toolbox

Key Features

• Algorithms available as MATLAB System objects and Simulink blocks
• Simulation of streaming, frame-based, and multirate systems
• Signal generators and I/O support for multimedia files and devices, including ASIO drivers and multichannel audio
• Design methods for specialized filters, including parametric equalizers and adaptive, multirate, octave, and acoustic weighting filters
• Filter realization architectures, including second-order sections and lattice wave digital filters
• Signal measurements for peak-to-peak, peak-to-RMS, state-level estimation, and bilevel waveform metrics
• FFT, spectral estimation, windowing, signal statistics, and linear algebra
• Algorithm support for floating-point, integer, and fixed-point data types
• Support for fixed-point modeling and C and HDL code generation
