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 ).
From 2007-2010, CHIRP partnered with organizations across the country to get licenses from Federal Communications Commission for a low power FM radio in urban areas. In 2009, CHIRP's president and vice president, Shawn Campbell and Jenny Lizak, were invited to the White House to discuss the issue of expanding low power FM radio with President Obama's technology team.

Chirp (also known as Asio Limited) was a technology company based in the UK. [1] Chirp was originally a research project from UCL and was incorporated as a UK limited company in 2012. [ 2 ] Chirp specialised in data-over-sound software development kits , [ 3 ] which converted data into audio signals, which could be transmitted to other devices ...
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).
Previously, the WDK was known as the Driver Development Kit (DDK) [4] and supported Windows Driver Model (WDM) development. It got its current name when Microsoft released Windows Vista and added the following previously separated tools to the kit: Installable File System Kit (IFS Kit), Driver Test Manager (DTM), though DTM was later renamed and removed from WDK again.
Wireless network cards for computers require control software to make them function (firmware, device drivers). This is a list of the status of some open-source drivers for 802.11 wireless network cards.
In computing, the Windows Driver Model (WDM) – also known at one point as the Win32 Driver Model – is a framework for device drivers that was introduced with Windows 98 and Windows 2000 to replace VxD, which was used on older versions of Windows such as Windows 95 and Windows 3.1, as well as the Windows NT Driver Model.
NDIS Miniport drivers can also use Windows Driver Model interfaces to control network hardware. [19] Another driver type is NDIS Intermediate Driver. Intermediate drivers sit in-between the MAC and IP layers and can control all traffic being accepted by the NIC. In practice, intermediate drivers implement both miniport and protocol interfaces.
