Question

16) Assume an analog signal with a frequency of 100 Hz needs to be acquired using USB6009 DAQ om sample mode N samples. Which of the following is a proper setting if you want to acquire at least one full cycle of the waveform each time? A. Sample rate of 100 Hz, N 100, and using differential analog input B. Sample rate of 2 kHz, N-10, and using single ended analog input C. Sample rate of 50 Hz, N 100, and using single ended analog input D. Sample rate of 1 kHz, N-50 and using differential analog input

Explanation / Answer

The correct answer is

B. Sample rate of 2 kHz, N=10 and using differential analog input.

Explanation: In this case Sample frequency = 12kHz. Hence, f(max) = 2/2 = 1 kHz and N = 10. Hence, the value of df = 1 x 103 / 10 = 100 Hz
