Description

The SPPPF Series of dual channel programmable, FIR filter platforms, are factory configured, turnkey solutions that cover the audio bandwidth to +20 kHz.  Each SPPPF-01 provides two independently tuned channels of on-board analog I/O with 9-bit, (512) tuning while each SPPPF-02 provides two independently tuned channels of on-board analog I/O with 8-bit, (256) tuning. SPPPF's are easy to use, plug-in modules with no external components, all packaged in a compact 2" x 2", low profile footprint.  Each SPPPF contains its own anti-alias and reconstruction filters along with ADC's, DAC's and analog I/O.  The SPPPF's provide brick wall, linear phase characteristics with low noise attenuation floors of -96 dB typical.  Sampling at 48 kHz, the fixed point DSP utilizes 32-bit math to achieve 24-bits of precision for digital FIR filters with shape factors from 1.03 to 1.50.

SPPPF's can be provided in several standard or custom frequency ranges utilizing a broad range of single or multi-rate brick wall algorithms.  All pre-programmed for your laboratory or field applications.

 

Features/Benefits:

  • Integrates the best of analog and digital signal processing to optimize standard and multi-rate FIR filter performance.
  • Each channel can be programmed independently.
  • Provides plug-in turnkey solutions with over 500 digitally programmable algorithms per channel.
  • All standard and custom solutions combine Brick-wall Low-Pass, Band-Pass solutions with linear phase performance.
  • Compact 2" x 2" dual channel design provides precision performance while minimizing board space requirements.

 

Applications

  • Sound and Vibration Testing
  • Signal Correlation / Data Analysis
  • Speech Analysis, Research, Pathology
  • Research and Development
  • Automatic Test Equipment
  • Data Acquisition Systems
