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 ).
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
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.
The case involves the 1994 killing of Timothy Blaisdell during a drug deal robbery on the island of Maui. Cordeiro’s first trial ended in a hung jury, with only one juror voting to convict him.
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.
