John Treichler, Rice DSP alum, distinguished visiting professor, and pioneer in the development of digital signal processing (DSP), has been elected to the National Academy of Engineering (NAE).

Now the president of Raytheon Applied Signal Technology of Sunnyvale, Calif., Treichler was cited by the NAE for his “contributions to digital signal processing and its applications to national intelligence gathering.” John is celebrated for inventing the “constant modulus” adaptive filtering algorithm, which is used to compensate for interference, such as multipath echoes, on communication signals.
