Title: The Innovations of Andrew Walston
Introduction
Andrew Walston is an accomplished inventor based in Toledo, OH. He has made significant contributions to the field of photonics and signal processing. His innovative work has led to the development of a unique patent that showcases his expertise and creativity.
Latest Patents
Walston holds a patent for a "Bipolar RF-photonic transversal filter with dynamically reconfigurable passbands." This architecture enables the realization of a FIR transversal filter with apodized, interlaced bipolar tap coefficients. The tap coefficients are varied through the control of optical powers emitted by an array of WDM laser sources. Additionally, the filter architecture allows for agile reconfiguration of tap coefficients in both polarity and magnitude. A chirped fiber-grating may be utilized to implement a series of wavelength-dependent tap-weights. This innovative filter design can eliminate the low-pass response centered at DC, allowing the placement of the center frequency of the first passband at a targeted intermediate frequency.
