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. Each has interesting useful properties. – Cort Ammon Feb 13, 2024 at 1:18 This seems a bit related to the question on Math StackExchange: Terminology re: continuity of discrete a*sin (t). – Mark S.

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 WebIt represents the distortion of a returned pulse due to the receiver matched filter [1] (commonly, but not exclusively, used in pulse compression radar) of the return from a moving target. The ambiguity function is defined by the properties of the pulse and of the filter, and not any particular target scenario.

WebThe Chirp-Z transform lets you evaluate any evenly-spaced set of frequencies along the unit circle (or even along an arc inside the unit circle, but we'll ignore that right now). Imagine you have a 256-element-long vector, and you'd like to compute the DFT at a more finely-spaced set of samples, but over a narrow range (the so-called "zoomed FFT".
WebThe values a, b, p are parameters. ω ( t) looks like the blue function here. with ω as such, y ( t) should be two chirps -- a sine wave whose frequency sweeps.
