Signal 1 Signal 2 AMA 0.5 ds 21. L18 The following statements describe A to D conversion of Signal 1 and Signal 2 shown. Which of the following is CORRECT? Note: the x-axis is time (seconds) and the y-axis has the same scale for both signals. A. For Signal 1, an appropriate sampling rate to prevent aliasing is 4 Hz. B. For Signal 2, an appropriate sampling rate to prevent aliasing is 20 Hz. C. The amplitude of Signals 2 is greater than the amplitude of Signal I. D. For Signal 2, the minimal sampling rate to prevent aliasing is 1 kHz. E. Sampling at the frequency of signal 1 is sufficient to prevent aliasing in the digital conversion of signal 2.
