What is essential bandwidth of FM signal?
"Essential bandwidth" is the portion of the signal spectrum that encompasses most of the energy of the original signal in the frequency domain.
What is the relation of frequency and bandwidth?
Frequency is a measure of the number of occurrences of a repeating event per unit time. The bandwidth of a frequncy is simply the difference between the upper and lower frequencies.
What is the relationship between bandwidth and frequency?
Bandwidth refers to the range of frequencies that a signal occupies, while frequency refers to the number of occurrences of a repeating event per unit of time. In general, wider bandwidth allows for more data to be transmitted at once, which can lead to higher data transfer rates. Additionally, the relationship between bandwidth and frequency is governed by the Fourier transform, where a wider bandwidth corresponds to a signal with a larger frequency range.
Band is to frequency as spectrum is to?
Bandwidth. Bandwidth refers to the range of frequencies over which a signal or device can operate effectively, similar to how band refers to a specific range of frequencies in a spectrum.
What is the relation between the bandwidth of a signal and after it has been encoded using spread spectrum?
there is no basic difference btw the BW. it is the same before & after the SS encoding
What is the relation between the bandwidth of a signal before and after it has been encoded using spread spectrum?
there is no basic difference btw the BW. it is the same before & after the SS encoding
What is difference between lifi and wifi?
In wifi, modulated signal is radio wave where as life modulated signal is light. It is visible electromagnetic spectrum and has higher bandwidth than wifi but has Line of sight limitation.
What is the connection between the bandwidth of a signal and the data rate that it represents?
The data rate (C) is equal to the bandwidth (B) times the logarithm base 2 of 1 plus the signal-to-noise ratio (S/N) (how much interference is introduced in the transmission of data)C = B x log2(1 + S/N)So your data rate is directly proportional to your bandwidth. If you increase your bandwidth, your data rate will also increase provided the signal-to-noise ratio isn't affected.
What is meant by a low pass signal?
A low pass signal whose bandwidth is much smaller than its center frequency, such as an AM signal. It is a a signal with its spectrum concentrated around zero frequency.
What is the relationship between frequency and bandwidth in terms of data transmission?
Frequency and bandwidth are closely related in data transmission. Frequency refers to the number of cycles per second that a signal oscillates at, while bandwidth is the range of frequencies that a signal occupies. In data transmission, higher frequencies allow for more data to be transmitted in a given amount of time, resulting in a wider bandwidth. Therefore, a higher frequency signal typically has a larger bandwidth and can carry more information.
What is bandwidth required for AM signal?
With full double sideband AM the bandwidth of the modulated signal is twice that of the baseband information signal. With suppressed carrier single sideband AM the bandwidth of the modulated signal is identical to that of the baseband information signal. With vestigial sideband AM the bandwidth of the modulated signal is somewhere between the above two cases, depending on how much of the vestigial sideband is included.
The relationship of the bandwidth required for double-sideband emitted carrier AM to the bandwidth of the modulating signal of?
In Amplitude Modulation (AM), specifically in the case of Double Sideband Suppressed Carrier (DSB-SC) or Full Carrier (DSB-FC) AM, the required bandwidth is twice the bandwidth of the modulating signal. If the modulating signal has a bandwidth of B Hz, the bandwidth required for AM would be 2B Hz. This is because both the upper and lower sidebands of the carrier wave are utilized in the modulation process, each consuming bandwidth equivalent to the original signal.
