  4. Chirp - Wikipedia

    en.wikipedia.org/wiki/Chirp

    A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal . [ 1 ] It is commonly applied to sonar , radar , and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum ).

  5. Chirp compression - Wikipedia

    en.wikipedia.org/wiki/Chirp_compression

    The chirp pulse compression process transforms a long duration frequency-coded pulse into a narrow pulse of greatly increased amplitude. It is a technique used in radar and sonar systems because it is a method whereby a narrow pulse with high peak power can be derived from a long duration pulse with low peak power.

    The Yaesu VX series is a line of two sequences of compact amateur radio handheld transceivers produced by Yaesu.There is a line of ultra-compact lower-power dual-band (2 m and 70 cm) transceivers that started with the VX-1R and was later updated with the VX-2R and VX-3R.

  7. CHIRP (algorithm) - Wikipedia

    en.wikipedia.org/wiki/CHIRP_(algorithm)

    CHIRP (Continuous High-resolution Image Reconstruction using Patch priors) is a Bayesian algorithm used to perform a deconvolution on images created in radio astronomy. The acronym was coined by lead author Katherine L. Bouman in 2016.

    SCPI was defined as an additional layer on top of the IEEE 488.2-1987 specification "Standard Codes, Formats, Protocols, and Common Commands". [4] The standard specifies a common syntax, command structure, and data formats, to be used with all instruments.

  9. USB communications - Wikipedia

    en.wikipedia.org/wiki/USB_communications

    A device that is high speed capable first connects as a full speed device (D+ pulled high), but upon receiving a USB RESET (both D+ and D− driven LOW by host for 10 to 20 ms) it pulls the D− line high, known as chirp K. This indicates to the host that the device is high bandwidth.
