Linear Chirp

Generates a real sine signal, which varies linearly in frequency over time

Description

The Linear Chirp component generates a sine wave signal at the output, $y$. Its equation is

where $k$  is the rate of change of frequency with respect to time,

The instantaneous frequency, $f$, of the generated sine wave varies linearly from ${f}_{0}$ at time ${T}_{0}$ to ${f}_{1}$ at time ${T}_{0}+{T}_{r}$ and is given by
