Best Answer

A shifted frequency refers to a change in the frequency of a signal, either increasing or decreasing its value. This change can result from modulation, mixing, or other signal processing techniques, leading to a new frequency offset from the original one. Shifted frequencies are commonly used in communication systems to carry information or for frequency translation purposes.

What is the apparent change in frequency of a sound as the source moves in relation to the listner?

The apparent change in frequency of a sound as the source moves in relation to the listener is known as the Doppler effect. If the source is moving towards the listener, the frequency heard is higher (shifted towards higher frequencies), and if the source is moving away from the listener, the frequency heard is lower (shifted towards lower frequencies).


What is the difference between frequency distortion and phase distortion?

Frequency distortion involves changes in the magnitude of different frequency components of a signal, leading to alterations in the overall spectral content. Phase distortion, on the other hand, refers to changes in the relative timing or alignment of different frequency components, affecting the shape of the signal waveform without altering its magnitude.


What causes the frequency of light from a moving object to change?

The frequency of light from a moving object changes due to the Doppler effect. If the object is moving towards an observer, the frequency of the light appears higher (blue-shifted) as the waves are compressed. If the object is moving away from the observer, the frequency appears lower (red-shifted) as the waves are stretched.


This is the change in color on the spectrograph as objects move toward or away from objects?

This phenomenon is known as the Doppler effect, where the frequency of light waves emitted by a moving object appears shifted depending on whether the object is moving towards or away from the observer. This shift in frequency causes a change in color on the spectrograph, with objects moving towards us appearing blueshifted (shifted towards the blue end of the spectrum) and objects moving away appearing redshifted (shifted towards the red end of the spectrum).


If a source of light is approaching us at 3000 kmsec then all its waves are?

have a higher frequency and shorter wavelength due to the Doppler effect.

What is intermediate frequency?

In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier frequency is shifted as an intermediate step in transmission or reception. [1] The intermediate frequency is created by mixing the carrier signal with a local oscillator signal in a process calledheterodyning, resulting in a signal at the difference or beat frequency. Intermediate frequencies are used in superheterodyne radio receivers, in which an incoming signal is shifted to an IF for amplification before final detection is done. The intermediate frequency stays the same for all signals, for example 455 kHz in an AM broadcast receiver.Conversion to an intermediate frequency is useful for several reasons. When several stages of filters are used, they can all be set to a fixed frequency, which makes them easier to build and to tune. Lower frequency transistors generally have higher gains so fewer stages are required. It's easier to make sharply selective filters at lower fixed frequencies.

How fast does light travel when being sucked in to a black hole?

exactly the speed of light, same as always. however it is doppler shifted. even very low frequency radio waves falling toward the black hole, by the time they hit the event horizon and vanish forever have blue shifted to become gamma rays. similarly even gamma rays rising away from the area immediately above the event horizon, by the time they escape have red shifted to become very low frequency radio waves.


Why you use 455kHz frequency as an intermediate frequency in communication?

The intermediate frequency in the superheterodyne receiver is chosen as the desired compromise between sensitivity and selectivity. 455kHz is used in AM broadcast applications, while 10.7mHz is used for FM. The IF stage is tuned for a steep skirt passband at that frequency, allowing only the desired heterodyned (shifted) input signal to make it through to the demodulator.


What radios contain intermediate frequency transformers?

AM (amplified modulation) radio contain the intermediate frequency transformer.it has IF to mixed the carrier signal into local oscillator signal in a process called heterodyning, resulting in a signal at the difference or beat frequency. Intermediate frequency are used in superheterodyne radio recievers, in which an incoming signals is shifted to an IF for amplication before final destination is done.


What is the opposite of shifted?

Not shifted.


What kind of echo does a bat hear from an object moving away from it?

A bat would hear a Doppler-shifted echo from an object moving away from it. This means the frequency of the echo would be lower than the frequency of the sound wave emitted by the bat. The bat's brain is able to interpret this change in frequency to understand the direction and speed of the object.


How do you write shifted in a sentence?

The sands have shifted, somewhat. As we passed the roadster, I shifted into second gear.
