The Baofeng UV-5R [note 1] is a handheld radio transceiver manufactured by the Chinese manufacturer Baofeng. This model was the first dual band radio (VHF/UHF) to be successfully distributed by a Chinese brand. [citation needed] It is inexpensive and relatively simple to use (though tedious to program without computer software).
CTCSS is an analog system. A later Digital-Coded Squelch (DCS) system was developed by Motorola under the trademarked name Digital Private Line (DPL). General Electric responded with the same system under the name of Digital Channel Guard (DCG).
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 ).
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.
The stationary phase method does not predict or deal with Fresnell ripples, so it is unable to offer any means by which these ripples can be minimized. As an example, the figure below shows a chirp spectrum with T. Δ F =250 obtained for a non-linear chirp aiming to match the Hamming window, using the methods described above. The figure shows ...
Instead of hearing the AFSK data, the user hears a short chirp from the radio speaker each time a data burst occurs. (The user must turn on this feature in the radio's option programming settings). A general option setting for all MDC systems is to enable or disable an acknowledgement (ack) data packet.
Ant Anstead is reflecting on how far his relationship with his ex-wife, Christina Haack, has come, more than four years after they split.. While appearing as a guest judge on the Feb. 19 episode ...
In digital communications, chirp spread spectrum (CSS) is a spread spectrum technique that uses wideband linear frequency modulated chirp pulses to encode information. [1] A chirp is a sinusoidal signal whose frequency increases or decreases over time (often with a polynomial expression for the relationship between time and frequency).
