8 Hz). What are the first five positive frequency components of the sampled signal? 2. There is no way to fix f*(t) after you have sampled. So, you must assure that the signal to be sampled has no frequencies higher than ωN = π/h. ). 36). 37. Sampling for accuracy: For a single-sine wave, the Nyquist criterion suggests to use more than two (2) samples/period (ωs > 2 ω0), but the reconstruction error via the zero-order hold is terrible. If we sample and hold with N ≥ 4 samples/period, then h = 2π/Nω0, then the maximum relative error = (( A sin 2π/N )/ A) = sin 2π/N and maximum relative error with h/2 shift is = sin π/N.
To avoid aliasing we must have λi within the primary strip in the s-plane, that is, |Im(λi)| < π/h. More manageably, |λi| < π/h i = 1, 2, …, n that is, poles within the circle of radius π/h. ⇒ hmax = π/ λ max ( A) where λmax is the largest eigenvalue of A (generally labeled the spectral radius). 9 s-plane to z-plane mapping for the primary strip in the s-plane. 38 s). 3 s and a desired accuracy in Ψ = 10−4?
