How does EZ pass work?
Radio wave signal a transponder.
What wave type is used by digital communications?
In digital communications, a digit is either a one or a zero, or an "on" or an "off" signal. The wave shape that is composed of "on's and off's" is the square wave.
What is output of not gate if sine wave is input?
Oh, dude, if a sine wave is the input to a NOT gate, the output will be the inverted sine wave. It's like flipping the wave upside down, you know? So, if the input is high, the output will be low, and vice versa. It's just how the NOT gate rolls, man.
Why is modulation necessary in radiobroadcasting?
Modulation in radio broadcasting is important because it is necessary to adjust the carrier signal so that the information in the modulating signal can be broadcasted. You must have modulation in order to transmit thru a radio wave.
What is difference between modulated wave and carrier wave?
Carrier Wave: A carrier wave is a high-frequency electromagnetic wave that is used as the "carrier" or the base signal in a modulation process. It is typically a pure sine wave with a constant frequency and amplitude. The carrier wave by itself does not carry any information; it serves as a vehicle to carry the information from one location to another. In AM and FM radio broadcasting, the carrier wave is the primary signal transmitted by the radio station. Modulated Wave: A modulated wave is the result of combining the carrier wave with an information signal, such as an audio signal or data. Modulation is the process of varying the characteristics of the carrier wave (either its amplitude or frequency) in accordance with the information signal. There are two common types of modulation: Amplitude Modulation (AM) and Frequency Modulation (FM). In AM, the amplitude of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave. In FM, the frequency of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave. The modulated wave contains the information that needs to be transmitted, and it can be demodulated at the receiving end to retrieve the original information.
What is meant by modes of propagation?
Modes of Propagation = different ways to continue and/or increase the number of a given species. Example: sexual reproduction.

how does layer of ionosphere affects in the propagation of radio waves?
The ionosphere layer affects radio wave propagation by reflecting or refracting the waves back to Earth. Different layers of the ionosphere interact with radio waves of different frequencies, allowing for long-distance communication via multiple hops. Changes in the ionosphere's density and ionization levels can also affect radio wave propagation by absorbing or attenuating signals.

Which wave cannot exist inside wave guide?
TEM TE modes (Transverse Electric) have no electric field in the direction of propagation. * TM modes (Transverse Magnetic) have no magnetic field in the direction of propagation. * TEM modes (Transverse ElectroMagnetic) have no electric nor magnetic field in the direction of propagation. * Hybrid modes are those which have both electric and magnetic field components in the direction of propagation
Is a radio wave longitudinal?
No, radio waves are transverse waves, meaning the oscillation of the wave is perpendicular to the direction of wave propagation. Longitudinal waves have oscillations parallel to the direction of wave motion.
What is the space wave propagation frequency?
Space wave propagation frequency is nothing special, it is the same frequency of the wave in question, for example WLAN Wifi produces 5.2 GHz radio wave from your computer or from router, so that would be the the space wave propagation frequency in question

What are the applications of sky wave propagation?
Sky wave propagation is used in long-distance radio communications. It is commonly used for broadcasting, military communications, and amateur radio operations. Sky wave propagation allows signals to be transmitted over long distances without the need for expensive infrastructure.

Lucien Boithias has written: 'Radiowave Propagation' -- subject(s): Tropospheric radio wave propagation
What is meant by ground wave propagation?
Ground wave propagation refers to the transmission of radio waves along the surface of the Earth. This type of propagation is commonly utilized for medium and long-distance communication, particularly in the AM radio band. Ground wave signals can follow the curvature of the Earth, allowing for extended coverage compared to line-of-sight transmission.
Is radio wave longitude or transverse?
A radio wave is an electromagnetic wave. Electromagnetic waves are transverse waves.
