WebOct 14, 2024 · A chirp, or swept sine signal can be expressed: x(t) = A(t) sin (2πɸ (t)), where ɸ is the phase, A is the amplitude, and t is the time. Most research has been done using linear or logarithmic chirp signals. Linear chirp signals provide equal energy stimulus at all frequencies, while the energy of a logarithmic chirp decreases with frequency. solidworks modify sketch pattern
