  • The theoretical approach encompasses common subjects covering principles of digital transmission, like notions of probability and stochastic processes, signals and systems, baseband and passband signaling, signal-space representation, spread spectrum, multi-carrier and ultra wideband transmission, carrier and symbol-timing recovery, information theory and error-correcting codes.


  • Variability at optical wavelengths and the brightness in the F606W passband suggest additional sources of luminosity such as starlight reflected from a circumplanetary ring system.

  • It doesn't have a lot of features, and in particular there's not much you can do to tweak the receiver (i.e. no filters, passband shaping, etc.) News

  • I do notice, so far, a lack of the "I can't wait to jump on someone in my passband" News

  • The product features low insertion loss, high dynamic range, flat & wide passband and blockband for high cascadability for both long haul & metro applications.
