20.6.1.1. Chirp

A chirp signal is a sinusoid whose frequency changes linearly from an initial value to a target one. The Chirp block outputs a chirp signal by the following equation.

\({y}=\sin {\left( 2 \cdot \pi \cdot \left( \frac{\left( {f_{target}}-{f_{initial}} \right) \cdot t^2}{2 \cdot t_{target}} + f_{initial} \cdot t \right) \right)}\)

where,

\(t\) is the simulation time.

\(y\) is the output.

Parameter(s)		Description
Initial Frequency	\(f_{initial}\)	Enter the Initial frequency of the signal.
Target Time	\(t_{target}\)	Enter the Time at which the frequency of the signal reaches \(f_{target}\).
Frequency at Target Time	\(f_{target}\)	Enter the Frequency of the signal at the target time.
