WebThe Chirp Signal block generates a sine wave whose frequency increases at a linear rate with time. You can use this block for spectral analysis of nonlinear systems. The block generates a scalar or vector output. The parameters, Initial frequency, Target time, and Frequency at target time , determine the block's output.

WebSep 5, 2015 · 1 In my opinion, the following code should produce a sine wave that has a frequency of 2 Hz at t = 20, but when I count the periods between t = 19 and t = 20, I count more than 3 periods. What am I doing wrong? clear all, close all, clc; t=linspace (0,20,10000); y=sin (2*pi* (1+ (5/100)*t).*t); plot (t,y); hold on; My plot: trigonometry matlab WebFeb 12, 2024 · The smoothly varying version is known as a "chirp," if you want to look up various popular chirps like a quadratic chirp or a cubic chirp.
