First we need to find out how many hours she worked during the whole week. WE multiply 12 by 7 and get 84. To find out how ,much she charges per hour, divide 600 by 84 and you get this amount.

You plan to acquire a sinusoidal signal that repeats 250 microseconds. What should be the minimum sampling rate of the digital s

Phoenix [80]

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
