Digital Signal Processing: Signals, Systems, and Filters
D-Filter is a multifaceted DSP software package that can be used to analyze, design,
and realize digital filters, and also to analyze discrete-time signals.
- It implements most of the classical methods for the design of nonrecursive (FIR)
filters such as the Fourier series and Remez methods and includes the use of the window
- Implements the bilinear transformation method for the design of recursive (IIR)
filters and includes modules that can be used to design filters that would satisfy
arbitrary prescribed specifications.
- Includes the standard realization methods that would enable the user to obtain
cascade and parallel direct canonic, state-space, and wave lattice digital-filter
- Provides functions that obtain the roots of polynomials, zero-pole plots, and
- Its modular top-down architecture and powerful graphical interface enable the
user to study and visualize many DSP phenomena such as the effect of coefficient
- Saves data in the form of standardized data structures that enable the user to
repeat or double-check the results obtained at every stage of the design process.
- Can be used by students to interactively learn the fundamentals of DSP and
- Can also be used by engineers and scientitists for real-life applications and
