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
Answer:
It will take rob 7 minutes to climb the stairs tomorrow.
Step-by-step explanation:
1000/25=40
Rob climbed 40 stairs per minute
280/40=7
Therefore, it will take rob 7 minutes to climb 280 stairs.
Answer:
Step-by-step explanation:Let a be the length of line
from question we know that
a+3 is another line
Here
a+(a+3)=15. ( Given in question )
2a = 15 -3
2a=12
a=12/2
a=6
Here a and a +3 are the length of the line
Finally ,6 and 9 are the lengths
