Chirped gaussian pulse
WebThe pulse is chirped. Chirp refers to a signal in which the frequency increases or decreases with time. We expect the dispersed pulse to be chirped because the … 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. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum). This signal type is biologically inspired and occurs as a ph…
