Chirp Z-transform - Wikipedia

WebThis is called a chirp signal for a very simple reason: it sounds like the chirp of a bird when played through a speaker. The key feature of the chirp system is that it is completely reversible. If you run the chirp signal through an antichirp system, the signal is again made into an impulse. WebJul 25, 2014 · One approach to generate a chirp signal is to concatenate a series of segments of sine waves each with increasing(or decreasing) frequency in order. This method introduces discontinuities in the chirp signal due to the mismatch in the phases of each such segments. Modifying the equation of a sinusoid to generate a chirp signal is a … on the day i die the shires

"WebThe method is a linear transform without energy loss, and is suitable for low signal-to-noise (SNR) environments. Moreover, the method can be effectively fulfilled based on the chirp-z transform (CZT), which prevents the brute-force search. Thus, the method reaches a favorable tradeoff between anti-noise performance and computational load. " - Chirp z-transform
