Instantaneous frequency law
NettetFor periodic motion, frequency is the number of oscillations per unit time. The relationship between frequency and period is. f = 1 T. 15.1. The SI unit for frequency is the hertz (Hz) and is defined as one cycle per second: 1 Hz = 1 cycle s or 1 Hz = 1 s = 1 s −1. A cycle is one complete oscillation. NettetSimulation examples involving non-Gaussian noise and signals with different instantaneous frequency laws are provided to demonstrate the effectiveness of the proposed approach.

A monocomponent signal is described in the time-frequency plane by a single "ridge." The set of monocomponent signals includes single sinusoids and signals like chirps. Generate a chirp sampled at 1 kHz for two seconds.
