What percentage of central frequency as bandpass for a narrow band amplifier?
central freqency of narrow band pass filter is the measure of difference between upper and lower cut off freqency
What is bandpass signal?
A bandpass signal, xc(t), is a signal whose one-sided energy spectrum is both: 1) centered at a non-zero frequency, fC, and 2) does not extend in frequency to zero (DC). The two sided transmission bandwidth of a signal is typically denoted by BT Hertz so that the one-sided spectrum of the bandpass signal is zero except in [fC − BT /2,fC + BT /2]. This implies that a bandpass signal satisfies the following constraint: BT /2 < fC. Fig. 1.1 shows a typical bandpass spectrum. Since a bandpass signal, xc(t), is a physically realizable signal it is real valued and consequently the energy spectrum will always be symmetric around f = 0. The relative sizes of BT and fC are not important, only that the spectrum takes negligible values around DC. In telephone modem communications this region of negligible spectral values is only about 300Hz while in satellite communications it can be many Gigahertz.
What is the need of digital modulation scheme?
The aim of digital modulation is to transfer a digital bit stream over an analog bandpass channel, for example over the public switched telephone network (where a filter limits the frequency range to between 300 and 3400 Hz) or a limited radio frequency band.
What is electronics and advantages and disadvantages of bassel filter?
A filter with a Bessel-type response has a phase response that is proportional to frequency over as wide a range of frequencies as possible. The idea is to simulate a delay line.
What operation Base Transceiver Station perform?
Transmitter section multiplexes baseband signals and modulates it with a carrier,then frequency translates IF to RF by frequency synthesizer and mixer. combines the power to transmit through a antenna before passing it through high power amplifier and bandpass filter. Receiver section passes RF through a band pass filter and low noise amplifier. Downconverts RF to IF by tunable local oscillator and mixer. further the signal is demodulated and demultiplexed before sending to ground communication equipments

How could one obtain the low and high frequency of the amplifire?
A low bandpass filter and a separate high bandpass filter should give the results required. These are usually in the form of crossover networks commonly used in speaker design. For low frequencies an LRC network is used (inductor, resistor, capacitor) and in high frequencies a simple electrolytic bipolar capacitor can be used. In more elaborate systems these can be active circuits (powered) or passive circuits as I previously mentioned.
What percentage of central frequency as bandpass for a narrow band amplifier?
central freqency of narrow band pass filter is the measure of difference between upper and lower cut off freqency
Why is bandpass filter used in fdm telemetry?
since fdm sends many message simultaneously the message signals must be bandpassed to send through the channel along with the error messages to reduce the bandwidth of the channel
Which device allow only frequencies in a certain range to pass through?
A bandpass filter is a device that allows only frequencies within a specific range to pass through, while attenuating frequencies outside of that range. This type of filter is commonly used in communication systems and audio equipment to select and isolate specific frequency bands.
What is the oil capacity for 2004 dyna wide glide?

What is center frequency?
Center frequency refers to the frequency at the midpoint between the upper and lower limits of a bandpass filter or a communication channel. It is a critical parameter in signal processing, telecommunications, and radio frequency engineering as it represents the frequency around which most of the signal energy is concentrated.
In audio electronics what are two common uses for a bandpass filter?
A bandpass filter is used to redirect certain frequencies, so it would be used to either attenuate (reduce), or boost. This would be used on your stereo, guitar amp or other audio processing/amplification device's tone control. For example; if you turned up the bass knob, it would allow a band of lower frequencies to pass to circuitry that would boost their signal for further processing or amplification.The "two common uses" would be attentuation and rejection. If this is for a school related project, I would strongly suggest that you do some more research for yourself, so that you properly understand it.
Why intermediate frequency transformers are used in modulation process?
They are used as adjustable bandpass filters in superheterodyne (Google it) recievers. They determine how well you can select the radio station you require, while rejecting those close to it. They work in a fixed frequency range where their characteristics can be optimised.Very many modern radio recievers use some form of the superheterodyne principle though the function of the IF Transformer (ie bandpass filter) can be realised digitally, as in mobile phones for example. For AM radio a bandwidth of 9 KHz at 450KHz is typical.

What is electronic filter?
Filter is an electronic device which passes specific frequency and attenuates all other.There are 4 types of filters: 1) Highpass - passes only high frequencies 2)Lowpass - passes only low frequencies 3)bandpass-passes only specefic band of frequencies 4)band reject-passes all frequencies excepting desired band
