QEDesign |
|
QEDesign is a design tool for developing digital filters. The user fills in menus to specify FIR and IIR filter performance. QEDesign automatically implements the filter, showing filter response in time, frequency plots. Specifications can be changed easily, automatically updating the response plots. Optional assembly code generators target the filter to popular DSP chips. |

Sample Rate Conversion System |
|
Provides fully automatic design of multi-stage polyphase filter networks for sample rate conversion systems. These filter networks provide optimized structures that will convert the sampling rate of signals within a specified distortion level. Sample Rate Conversion System filter can be imported into DSPworks for applying directly to signals. Optional assembly code generators target the filter to popular DSP chips. |

Multirate Filter Design System |
|
Allows the design of very narrow Lowpass or Bandpass FIR filters. Provides fully automatic design of multi-stage polyphase filters. A multirate filter provides computational efficiencies that are not possible in a single fixed sample rate. The automation provided by the Multirate Filter Design System eliminates the possibility of mathematical calculation error and reduces the overall filter design time. Also designs Narrowband Highpass, Wideband Lowpass, and Wideband Highpass filters. Optional assembly code generators target the filter to popular DSP chips. |
|
Quadrature Mirror Filter Bank Design System |
|
Automates and simplifies the design of sub-band coders. Quadrature Mirror Filter Banks are a specialized form of multirate filtering that provides computational simplifications and perfect signal re-construction. The automation provided by QMFB reduces design time, simplifies filter specification and eliminates computational error. Optional assembly code generators target the filter to popular DSP chips. |
 |
DSPworks |
|
DSPworks is a system that provides data acquisition, signal generation, waveform manipulation and display. The system integrates with DSP boards from Momentum Data Systems and popular boards from other commercial suppliers. It also imports the filter coefficients from any of Momentum's filter design software packages. Browse our download area for free demo software. |

Code Generators |
|
Each code generator is a stand-alone utility which reads coefficient files generated by the MDS Filter Design and Analysis Systems. The code generator generates highly optimized assembly language programs for both IIR and FIR filters. The programs can be modified to accommodate different I/O capabilities, or incorporated as subroutines in a larger system. |
