Answer: F = 25.1 kHz
Step-by-step explanation:
Time (period) = 250 × 10^-6 s
Let's first calculate the folding frequency. Given by
NF (rad s-1) = π/Δt
where NF = Nyquist frequency
t = time increment between observations.
The original signal must be filtered by analog or physical methods to remove all frequencies higher than the Nyquist frequency before the signal is sampled or digitized.
F = 3.143/0.00025
F = 12566.37Hz
minimum sampling rate = 2F
2 × 12566.37 = 25132.74Hz
minimum sampling rate = 25.1 KHz
Why is the sky orange and red at sunrise and sunset?
Gases absorb orange and red light.
Blue wavelengths are absorbed by the atmosphere.
The thick atmosphere scatters all but longer wavelengths.
Only short wavelengths are radiated from the Sun in the morning and evening.
Answer:
