Answer:
In order to prevent the aliased frequency from we need to sample at with a sampling frequency that is minimum 2 times the highest frequency where information exit i.e 2 × 750 = 1500 Hz
Explanation:
The explanation is shown on the first and second uploaded image
The unit represents a value that is one order of magnitude larger than a decimeter is a meter
<h3>Further explanation </h3>Magnitude is something that can be measured or counted
The principal amount is the amount that has been determined based on the agreement of the scientists
Derivative magnitude is a quantity derived from the principal amount
There are 7 main quantities that have been determined based on international standards, namely:
- 1. Length, meters (m)
- 2. Time, second (s)
- 3. Mass, kilograms (kg)
- 4. Temperature, kelvin (K)
- 5. Light intensity, candela (cd)
- 6. Electric current, amperage (A)
- 7. Amount of substance, mol (m)
The length of the principal is to indicate the distance between two points in a place
The symbol is usually expressed in l, length
Length measurements can be used by several measuring instruments such as ruler, caliper length, meter, screw micrometer
The main length unit consists of 7 units other than other units of length such as inches, miles, yards, feet:
- Kilometers, km
- Hectometer, hm
- Dekameter, dam
- Meters, m
- Decimeter, dm
- centimeters, cm
- millimeters, mm
Each one unit descends then multiplied by 10, and if one unit increases then divided by 10
Conversion of other mass units:
mm millimeters = 10⁻³ m
km kilometers = 10³ m
µm micrometers (mcm) = 10µm
nm nanometers = 10⁻⁹ m
Gm gigameters = 10⁹ m
ρm picometers = 10⁻¹² m
An order of magnitude used base ten number.
If numbers differ by one order of magnitude, so the number is about 10 times different in quantity . If values differ by two orders of magnitude, they differ about 100.
The decimeter unit is located between the centimeter and meter.
Decimeter value = 10⁻¹m, centimeter = 10⁻² m, so that the unit represents a value that is one order of magnitude larger than a decimeter is meter
