    Additional for software-defined radio / digital baseband receivers: Waterfall display support or not. Both In-phase and Quadrature signals: I-Q signal-bandwidth. Number of A/D converter bits (determines the maximum achievable dynamic range within the I-Q signal-bandwidth; 10 bits approximately equals 60 dB)

  6. Waterfall plot - Wikipedia

    en.wikipedia.org/wiki/Waterfall_plot

    Waterfall plots are often used to show how two-dimensional phenomena change over time. [1] A three-dimensional spectral waterfall plot is a plot in which multiple curves of data, typically spectra, are displayed simultaneously. Typically the curves are staggered both across the screen and vertically, with "nearer" curves masking the ones behind.

    DO-178B, Software Considerations in Airborne Systems and Equipment Certification is a guideline dealing with the safety of safety-critical software used in certain airborne systems. It was jointly developed by the safety-critical working group RTCA SC-167 of the Radio Technical Commission for Aeronautics (RTCA) and WG-12 of the European ...

  8. Software-defined radio - Wikipedia

    en.wikipedia.org/wiki/Software-defined_radio

    Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]

  9. OpenHPSDR - Wikipedia

    en.wikipedia.org/wiki/OpenHPSDR

    The OpenHPSDR (High Performance Software Defined Radio) project dates from 2005 when Phil Covington, Phil Harman, and Bill Tracey combined their separate projects to form the HPSDR group. [1] It is built around a modular concept which encourages experimentation with new techniques and devices (e.g. SDR , Envelope Elimination and Restoration ...
