Request InfoGage-Line Technology Inc.Gage Applied Technologies has introduced finite impulse response filter field-programmable gate array (FPGA) technology in its high-resolution 14-bit digitizers, enabling users to filter digitized data in real time with a customizable finite impulse response filter. Filtering of analog voltage signals removes noise and emphasizes features of interest. With the numerical filtering of digitized waveform data now available, more complex methods such as moving average filters and Gaussian filters can be implemented. The technology is available as an optional FPGA image that can be installed on...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 2/2/2024Optical Processors and FilterThe WaveShaper® 1000A, 4000A, and 500B from Coherent are programmable optical processors and a filter, respectively, capable of testing optical components and networking systems in the U- and...Photonics Spectra October 2023 IssueCoated Glass FiltersNVIS Coated Glass Filters from Abrisa Technologies are designed for night vision imaging systems and lighting displays.
