WebFeb 1, 2000 · The mean spike frequency gradually decreases to 61 spikes/s toward the end of the chirp cycle at ϕ = 0.9. It increases again in phase with the opening movement of the first syllable at ϕ = 0.9–0.1. Thus there is a modulation of the spike rate within the chirp cycle with the major spike activity occurring in phase with the generation of the ... WebBelow are several examples of using the chirp function to generate linear or quadratic, convex, and concave quadratic chirps. Generate a linear chirp sampled at 1 kHz for 2 seconds. The instantaneous frequency is 100 Hz at t = 0 and crosses 250 Hz at t = 1 second. tlin = 0:0.001:2; ylin = chirp (tlin,100,1,250);

I assumes that I can configure the number of chirps in a frame by setting in < frameCfg >, which is 2 in the demo. Thus, according to the attached figure, there should be two chirp cycles in each frame. WebThe following formulas give the instantaneous frequency (in Hz) of the signal generated by chirp ().

In the following, ‘Hz’ should be interpreted as ‘cycles per time unit’; there is no assumption here that the time unit is one second. The important distinction is that the units of rotation are cycles, not radians. WebChirp generation.
