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 ).
On Mac OS X 10.4-10.7.x, IntelliPoint features can be accessed by opening Microsoft Mouse in System Preferences. [ 2 ] Depending on the software version and specific mouse product, users can define mouse buttons to run any executable program or file they desire (or a control key + letter combination) and can even define buttons for different ...

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 ...
Software versioning is the process of assigning either unique version names or unique version numbers to unique states of computer software. Within a given version number category (e.g., major or minor), these numbers are generally assigned in increasing order and correspond to new developments in the software.
Chirp spread spectrum was originally designed to compete with ultra-wideband for precision ranging and low-rate wireless networks in the 2.45 GHz band. However, since the release of IEEE 802.15.4a (also known as IEEE 802.15.4a-2007), it is no longer actively being considered by the IEEE for standardization in the area of precision ranging.
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.
