What else can I help you with?
What is changing the height of the carrier wave to match the signal called?
It is called "frequency modulation"
What causes an electric humming sound in equipment?
The sounds are caused by the oscillations of the frequency changing from positive to negative when voltage is applied to electrical equipment.See related links below.
Why semi log paper is used for frequency vs gain plot?
the sem-ilog paper is used to draw the data that are changing with an exponential relationship. it is preferable when one variable covers a large range of values and other has only a restricted range.
When was Changing Times - film - created?
Changing Times - film - was created on 2004-12-08.
Is periphrasis a scheme or a trope?
trope because scheme involves changing the structure of a sentenc while trope involves changing the meaning.
What is changing amplitude or frequency called?
modulation
If the frequency in AM does not change then how are these sidebands formed?
The process of changing the amplitude of the "carrier" so as to add information to it (modulation) doesn't change the frequency of the carrier. But it does create energy at two other newfrequencies.The new frequencies are equal to (carrier frequency) plus and minus (the modulating frequency). These are referred to as the upper and lower sidebands.The upper sideband is an exact copy of the modulating signal, but with every component of it shifted up by an amount equal to the carrier frequency. The lower sideband is a mirror image of the upper sideband, with every frequency component in it reflected about the carrier frequency.
Does changing the frequency change the amplitude?
No, changing the frequency of a wave does not change its amplitude. Amplitude is a measure of the maximum displacement from the equilibrium position, while frequency is the number of oscillations per unit time. These two properties are independent of each other.
If amplitude decreases what happens to frequency?
If the amplitude decreases, the frequency remains unchanged. Amplitude refers to the magnitude of the signal, while frequency refers to the number of oscillations per unit of time. Changing the amplitude does not affect the frequency of the signal.
Changing the amplitude or frequency of waves is called?
Modulation.
How do waves carry signals?
Waves can be varied (modulated) by either changing amplitude (amplitude modulation AM) or changing frequency (wavelength) (frequency modulation FM). The modulations are used to carry the information signal.
What effect does frequency have on the amplitude of a wave?
Frequency does not have a direct effect on the amplitude of a wave. The amplitude of a wave is determined by the energy of the wave, while frequency refers to the number of wave cycles in a given period of time. Changing the frequency of a wave will not alter its amplitude.
Would amplitude increase if frequency increased?
No, amplitude is not directly related to frequency. Amplitude refers to the intensity or magnitude of a wave, while frequency refers to the number of times a wave oscillates in a given period. Changing the frequency of a wave will not automatically change its amplitude.
Does Amplitude change frequency?
No, amplitude and frequency are independent of each other. Amplitude refers to the intensity or strength of a wave, while frequency refers to the number of complete oscillations of a wave that occur in a given amount of time. Changing the amplitude does not affect the frequency of a wave.
Is frequency inversely proportional to amplitude?
No, frequency and amplitude are independent of each other. Frequency refers to the number of oscillations or vibrations per unit of time, while amplitude is the magnitude or size of those oscillations. Changing the frequency does not automatically change the amplitude of a wave or vibration.
What is the modulation of frequency?
It is a device or electronic circuit that changes the frequency of an oscillator according to the amplitude of modulating signal. For instance, if the modulation is linear, the modulator changes the frequency proportional to the amplitude of the modulating voltage.
How does changing the amplitude change the frequency?
There's no connection between amplitude and frequency. Either one can change, and often does, with absolutely no effect on the other.
