Description

Design engineers now have an off-the-shelf precision, dual channel hardware solution for development of digital FIR filters that can be used in production subassemblies. Designers can generate FIR filter characteristics in a MatLab™ V5.3 or V6.0 environment and directly load standard or custom coefficient sets into the SPPDM-01 platform via an RS232 interface located on the users field programmable subassembly or from the SPPDB-01 development board.

By utilizing the SPPDF-01 hardware with the enclosed MatLab GUI, generated coefficients are loaded directly into the removable SPPDM-01 platform for insertion into finished EOEM products. This unique capability minimizes product development and manufacturing cycle times while providing precise unit-to-unit product matching in a small 2" x 2" footprint that can be reconfigured or upgraded in the field.

SPPDM-01 FIR filter platforms operates over a 100 Hz to 20 kHz audio frequency range. Each channel can be configured to provide up to 9-bits of filter frequency programmability per channel. This dual channel DSP design solution contains anti-alias and reconstruction filters along with ADC's and DAC's offering low noise and distortion signal processing with THD approaching -100 dB. Sampling at 48 kHz the fixed point DSP utilizes 32-bit math to achieve 24-bits of precision.

Features/Benefits:

  • Compact 2" x 2" dual channel design combined with large program memory (256 k EE-Prom) and 4-Mbits of flash memory optimizes DSP processing power in minimal board space.
  • SPPDB-01 development hardware offers rapid set-up, programming and performance evaluation, shortening the product development cycle while insuring high precision field programmable installation.
  • Field programmability of coefficient sets, analog I/O and storage for 100's of application specific FIR filters provide designers with unmatched design, implementation and field upgrade flexibility.

 

 

Applications

  • Brick-Wall; High-Pass, Low-Pass, Band-Pass, Band-Reject and Multi-Rate filters with Linear Phase and Signal Generators for Data Acquisition Systems.
  • Speech analysis, research, pathology
  • Sound and vibration testing
