A continuous-time signal x (t) = Δ((t = 1)/2) is sampled at three rates: 10, 2, and 1 Hz. Sketch the resulting sampled signals. Because x (t) is timelimited, its bandwidth is infinite. However, most of its energy is concentrated in a small band. Can you determine the reasonable minimum sampling rate that will allow reconstruction of this signal with a small error? The answer is not unique. Make a reasonable assumption of what you define as a "negligible" or "small" error.
