Question
In case the sound from the engine of a vehicle is modelled by the function
y(t) = cos[ω(t + τ) + θ]
where time delay=τ & phase=θ
Determine the frequency & period of the signal u(t) when
a)[ω, τ, θ] = [π/3, 1/2, π/2]
b)[ω, τ, θ] = [3π/4, 1/2, π/4]
N.b time should be in seconds & frequency in Hertz.
c) y(t) = e-atu(t) for t≥0 & y(t) = 0 for t<0 where a>0 is a constant
The function above defines the model of the decay of the vibration of a vehicle engine.
i.Make a sketch of the signal y(t) & determime its fourier transform.
