What property of an electromagnetic wave changes when the wave is encoded with analog information?

Physics

Licemer1 [7]3 years ago

Answer:

Amplitude and Frequency

Explanation:

Analog signals are composed of continuous waves that can have any values for frequency and amplitude. These waves are smooth and curved.

Radio transmissions are a combination of two kinds of waves: audio frequency waves that represent the sounds being transmitted and radio frequency waves that "carry" the audio information. All waves have a wavelength, an amplitude and a frequency as shown in the figure. These properties of the wave allow it to be modified to carry sound information.

The two most common types of modulation used in radio are amplitude modulation (AM) and frequency modulation (FM). Frequency modulation minimizes noise and provides greater fidelity than amplitude modulation, which is the older method of broadcasting . Both AM and FM are analog transmission systems, that is, they process sounds into continuously varying patterns of electrical signals which resemble sound waves.

The peak current through a resistor is 2. 0 aa. part a what is the peak current if the resistance rr is doubled?
timofeeve [1]

When the resistance R is doubled, I = 1 A

One of the most fundamental and significant principles controlling electrical and electronic circuits is called Ohm's Law. For a linear device, it relates current, voltage, and resistance.

According to Ohm's Law, the current flowing through a circuit is inversely proportional to the resistance in the circuit and directly proportional to the applied potential difference.

Ohm's law can be written mathematically as follows:

V = IR

Where:

   V = voltage expressed in Volts

   I = current expressed in Amps

   R = resistance expressed in Ohms

If any two quantities are known, the third can be computed by manipulating the formula.

   I= V/R

   R= V/I

What does the vibrating object do to the air particles around it ?
dimulka [17.4K]

Answer:

When an object vibrates, it causes the molecules in the air around it to move. These molecules collide with nearby molecules, forcing them to vibrate as well. As a result, they collide with more surrounding air molecules.

If a current of 2.4 a is flowing in a cylindrical wire of diameter 2.0 mm, what is the average current density in this wire?
Gnom [1K]

The average current density in the wire is given by:

J=\frac{I}{A}

where I is the current intensity and A is the cross-sectional area of the wire.


The cross-sectional area of the wire is given by:

A=\pi r^2

where r is the radius of the wire. In this problem, r=\frac{d}{2}=\frac{2.0 mm}{2}=1.0 mm=0.001 m, so the cross-sectional area is

A=\pi (0.001 m)^2=3.14 \cdot 10^{-6} m^2


and the average current density is

J=\frac{I}{A}=\frac{2.4 A}{3.14 \cdot 10^{-6} m^2}=7.64 \cdot 10^5 A/m^2
