Features

Easy to Use and Learn

  • Well-organized palettes for drawing and solving systems with a single mouse click
  • The first mouse-driven interactive drawing tool entirely based on Mathematica's built-in functions, graphics primitives, and palettes
  • Powerful functions constructed so that you only need to specify the minimum amount of information when modeling or solving a system
  • Functions that generate schematics for arbitrary symbolic system parameters
  • Visualization tools for drawing publication-quality schematics and viewing system models and responses
  • The graphical representation of a system is not a static bitmap image; it changes automatically when you change system parameters
  • Large schematics can consist of replicas of simpler schematics; you can write a code to automate drawing for an arbitrary number of repeated parts
  • Extensive online documentation including illustrative application examples and comprehensive reference with the Help Index
  • Requires a minimum understanding of basic system theory and signal processing

Powerful Modeling and Simulation Environment

  • Symbolic signal processing, a unique feature of SchematicSolver not available in other software, brings you computation of transfer functions as closed-form expressions in terms of symbolic system parameters
  • Computes the transfer function matrix of a multiple-input multiple-output (MIMO) system
  • Finds the closed-form response (signals at nodes of the system) directly from the schematic; the derived result is the most general because all system parameters, inputs, and initial conditions (states) can be given by symbols
  • Performs fast and accurate simulations of discrete-time (digital) and continuous-time (analog) systems, such as velocity servo, adaptive LMS, automatic gain control (AGC), quadrature amplitude modulation (QAM), efficient multirate, dynamic feedback and control, and nonlinear discrete-time systems, as well as square-law envelope detectors, thermodynamics of a house, high-speed recursive filters, Hilbert transformers, and digital filters.
  • Models systems that work with symbolic complex signals, such as Hilbert transformers
  • Carries out symbolic optimization of the system response and mixed symbolic-numeric signal processing
  • Performs signal processing in a traditional numeric way

Fast and Reliable

  • A single mouse click symbolically simulates, solves, or implements a system directly from the schematic, letting you set up the equations describing the system, compute the system response and transfer functions, and generate the implementation function
  • Helps you generate efficient multirate implementations by working in the symbolic domain
  • Provides symbolic derivations of important closed-form relations between parameters of a system, such as the power-complementary property of high-speed digital filters
  • Finds closed-form expressions of output signals for known stimuli given by closed-form expressions and for certain classes of nonlinear systems
  • Solves systems with unconnected elements; signals at unconnected element inputs are automatically generated as unique symbols
  • Helps you design systems: for known symbolic transfer function, impulse, or step response, you can generate the schematic of the system and find the system parameters

Implementation of Discrete-Time Systems

  • Automatic generation of the software implementation of linear and nonlinear discrete systems directly from the schematic
  • Generated implementation functions can process symbolic samples one by one
  • For a symbolic input sequence you can compute the symbolic output sequence with both the system parameters and the initial conditions (states) specified by symbols
  • Sets up symbolic implementation equations directly from the schematic
  • You can process a list of data samples for a given transfer function; the transfer function is automatically implemented as a single-input single-output transposed direct form 2 IIR discrete system
  • Provides functions for upsampling and downsampling discrete signals and for generating most common discrete signals, such as impulse, step, ramp, sinusoidal or exponential, and random (noise) sequences.
  • Includes functions to plot frequency response and sequences that represent discrete signals, discrete Fourier transform spectra, and discrete-time Fourier transform spectra
