Digitizers utilize FIR filter technology.

Press Release Summary:

Finite Impulse Response Filter technology is available as optional FPGA image that may be installed on 14-bit digitizers. Numerical filtering of digitized waveform data allows complex filtering methods, such as moving average filters and Gaussian filters, to be implemented. Filtering of data is performed in real-time during transfer of data through PCI bus to PC, and is done transparently with no processing required by host PC's CPU.

Gage Applied Technologies Unveils New On-board Finite Impulse Response Filter FPGA Technology

Montreal, Canada (March 29, 2005) - Gage Applied Technologies, worldwide leader in design and manufacture of high-performance PC-based digitizer and oscilloscope cards, has introduced new on-board Finite Impulse Response (FIR) Filter FPGA Technology in its high-resolution 14-bit digitizers. This new FIR Filter Technology allows users to filter digitized data in real-time with a completely flexible and user customizable FIR filter.

Filtering of analog voltage signals is a powerful method for removing unwanted signal features (like noise) and emphasizing signal features of interest. Traditional analog filters are usually limited to rather simple filtering methods, such as low-pass filtering, high-pass filtering and band-pass filtering. Numerical filtering of digitized waveform data, such as that now available on-board Gage's 14-bit digitizers, allows much more complex filtering methods such as Moving Average Filters and Gaussian Filters to be implemented.

Gage's new FIR Filter Technology is available as an optional Field Programmable Gate Array (FPGA) image that may be installed on its line of 14-bit digitizers. The image allows processing by an FIR filter with up to 20 taps. FIR filtering of digitized data is performed in real-time, during the transfer of data through the PCI bus to the PC, so that the analysis does not reduce the repetitive signal capture rate of the digitizer. Data is transparently filtered with no processing required by the host PC's CPU.

The FIR Filter Technology was designed to be transparent to Gage's standard CompuScope drivers for Windows, so that no special software is required. In fact, the optional FIR Filter Technology can be implemented by existing Gage customers on cards already in use in the field without requiring the card to be sent back to Gage to be reprogrammed. "We listened to our customers carefully. They told us that they wanted this type of FIR Filtering Technology on-board our digitizers, and they wanted to be able to implement it without disturbing their existing system setup," said Eric Gillas, Gage General Manager. "It is all about offering the best technology as quickly and as easily as possible to our customers. Additional application specific FPGA technology for fast, custom on-board data analysis is already in the works," Gillas added.
