Different between power transistor and transistor that used in small signal?
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
Why high frequency carrier is required for a communication system?
to shift the frequency of information signal ,at the frequency domain to a higher frequency ...so the information can be transmitted to the receiver .
Why is it desirable to have the modulation index of an AM signal as large as possible without overmodulating?
It uses the maximum power available to the transmitter and makes the signal more readable at a greater distance.
What is relation between roll off factor bandwidth and bit rate?
The roll-off factor of a digital filter defines how much more bandwidth the filter occupies than that of an ideal "brick-wall" filter, whose bandwidth is the theoretical minimum Nyquist bandwidth. The Nyquist bandwidth is simply the symbol rate expressed in Hz: Nyquist Bandwidth (Hz) = Symbol Rate (Sym/s) However, a real-world filter will require more bandwidth, and the excess over the Nyquist bandwidth is expressed by the roll-off factor. Suppose a filter has a Nyquist bandwidth of 100 MHz but actually occupies 120 MHz; in this case its roll-off factor is 0.2, i.e. the excess bandwidth is 0.2 times the Nyquist bandwidth and the total filter pass-bandwidth is 1.2 times the Nyquist bandwidth.
Does a low bandwidth signal have more power than a high bandwidth signal?
A low bandwidth signal does not have more power.
What are the major power challenges of 4G MANET?
The forth generation of wireless technology offers increased bandwidth, mobility and the signal's range. Increasing the signal power, a device requires more electrical power that will be consumed during signal transmission.
What signal has wider bandwidth sine wave with frequency 100HZor 200HZ?
The signal with a frequency of 200Hz has a wider bandwidth compared to a signal with a frequency of 100Hz. Bandwidth is determined by the range of frequencies present in a signal, so a higher-frequency signal will have more frequency components and thus a wider bandwidth.
Why high frequency signal is more affected by noise compare to low frquency signal?
AS FREQUENCY INCREASE THE BANDWIDTH INCREASE. AS WE KNOW NOISE HAVE LARGER BANDWIDTH. SO ITS AFFECT HIGH FREQUENCY SIGNAL. BUT LOW FREQUENCY SIGNAL HAVE LOW BANDWIDTH SO IT IS LESS AFFECTED BY NOISE. ALSO WE KNOW QUALITY FACTOR= CUTOFF FREQUENCY / BANDWIDTH. SO AS FREQUENCY INCREASE B.W. INCREASE SO QUALITY DEGRADE. CUTOFF FREQUNCY AND THE TERM FREQUENCY (USED HERE) IS DIFFERENT. CUTTOFF FREQUNCY IS USED IN FILTER. PRABIR KUMAR SETHY prabirsethy.05@gmail.com
What is spectral band width?
Spectral bandwidth refers to the range of wavelengths or frequencies over which a signal, such as light or sound, is transmitted or detected. It is a measure of the spread of frequencies in a signal and can provide information about the resolution or clarity of the signal. A wider spectral bandwidth typically means more information is being conveyed, while a narrower bandwidth may result in a more focused or selective signal.
What is difference between amplitude modulation and frequency modulation with respect to signal to noise ratio?
In FM noise is low as compared to AM. The AM signal covers more distance than FM signal that's why it gets more distorted.How ever the information in AM signal does not lose but the noise effects it more than that of FM signal,so we get signal with more noise than that of FM signal For FM Carson's rule Main article: Carson bandwidth rule A rule of thumb, Carson's rule states that nearly all (~98%) of the power of a frequency-modulated signal lies within a bandwidth of where , as defined above, is the peak deviation of the instantaneous frequency from the center carrier frequency . Noise quieting The noise power decreases as the signal power increases; therefore the SNR goes up significantly. Thanks, By tauseef ahmed
What is a bandwidth in computer science?
Bandwidth is something like a space; bandwidth is proportional to the signal rate. if the signal rate is low then the bandwidth is high and vice versa. bandwidth carry the amount of information in a specific time period.For example if 1 person travel in 1 car then bandwidth will increase or if 4 person travels in 1 car then bandwidth will decrease. :)
What key features affect the channel capacity?
Key features that affect channel capacity include bandwidth, signal-to-noise ratio, and modulation technique. A wider bandwidth allows for more data to be transmitted, while a high signal-to-noise ratio enables better accuracy in data transmission. The modulation technique used can also impact channel capacity by determining how efficiently the available bandwidth is utilized.
What do mean by high bandwidth?
The biggest difference between high and low bandwidth is latency. The lower the bandwidth the more time the computer spends trying to download the data.
What is the purpose of broadband?
The bandwidth of a signal is related to how fast you can transmit information over that signal. Signals with large (or broad) bandwidth can transmit more information (data) in a given amount of time, so this results in faster download times.
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.
Importance of using single side bands in radio communication?
The two major advantages are the signal takes 1/2 the bandwidth and it allows more of the power to be applied into the narrow band thereby increasing strength.
