WebDescription. y = chirp (t,f0,t1,f1) generates samples of a linear swept-frequency cosine signal at the time instances defined in array t, where f0 is the instantaneous frequency at time 0, and f1 is the instantaneous frequency at time t1. f0 and f1 are both in hertz. If unspecified, f0 is 0, t1 is 1, and f1 is 100. http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/signal/chirp.html
