1. From the lowest frequency to the highest frequency. For telephone grade audio, it's 300 Hz to 3300 (or 3400 ) Hz. For other signals, you need to know the lowest and highest frequencies.
2. Your question (can BB signal be transmitted...) cannot be answered. As it stands, the answer is no. Reword the question so that it can be answered.

What is baseband connection?
Electrical signals are found in different parts of the frequency spectrum. A baseband signal is an "original" signal that directly conveys the frequency range of the original: a hi-fi audio signal is commonly 20 Hz to 20 kHz, analog video (European) is 50 Hz to 5 MHz. A baseband signal *does not* use a modulated carrier, no matter how high or low its frequency. Any signal that *does* use modulation is *not* a baseband signal. Radio (and other) transmission systems use the baseband signal to modulate a carrier before sending. On reception, the modulation is extracted to become a copy of the original baseband signal.
Is it right that a television channel is characterized by frequency of transmitted signal?
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
What is the importance of De-emphasis network in FM receiver?
One characteristic of the FM process is that the noise is distributed such that it's lowest at the bottom frequency of the channel, and increases steadily as you move up the channel. Knowing this, pre- and de-emphasis is the clever trick we use to decrease the noise in the FM communications channel. Here's how it's done:At the transmitter, pre-emphasis is applied to the baseband information before modulation ... the main channel L+R and L-R signals, plus any subcarriers that the station carries. Pre-emphasis is intentional distortion of the frequency response across the baseband that attenuates the low-frequency end, and progressively amplifies everything as you move up in frequency. The result of this operation is what actually gets transmitted.The receiver is responsible for doing just the opposite. It applies de-emphasis immediately after demodulation ... it attenuates the high-frequency end of the baseband, and progressively amplifies everything as you move down in frequency.If the pre- and de- are accurately matched, then the frequency response of the system winds up flat across the baseband, which is what we want. But ... by attenuating the higher frequencies, the receiver also changes the noise-content of the baseband, from a distribution that gets worse as you move up in frequency, to a distribution that's flat across the channel.
Deacribe a method for frequency translation?
let me explain it : The transfer of signals occupying a specified frequency band, such as a channel or group of channels, from one portion of the frequency spectrum to another, in such a way that the arithmetic frequency difference of signals within the band is unaltered. One key operation is the frequency translation of a signal spectrum from one center frequency to another. Conversions between baseband and bandpass representations (modulation and demodulation) are special cases of this. Conceptually, the most simple case is the (complex) I/Q-mixing. Here the input sequence is multiplied by a complex exponential signal corresponding to the local oscillator (LO) frequency fLO.(2.1)It follows directly from the properties of Fourier transform that I/Q mixing causes a pure frequency translation of the signal spectrum:(2.2)Complex mixing used to produce pure frequency translation of input spectrum.
Differences between baseband and broadband?
Baseband is a type of transmission that uses current to send a signal over the wire as digital wave. Broadband uses analog signal to transmit thru different frequencies, which increases the amount of data carried at one time.
Whats the difference between baseband and broadband?
In Baseband, data is sent as digital signals through the media as a single channel that uses the entire bandwidth of the media. Baseband communication is bi-directional, which means that the same channel can be used to send and receive signals. In Baseband no frequency-division multiplexing is not possible. (Multiplexing (short muxing) is a process where multiple analog message signals or digital data streams are combined into one signal over a shared medium.)Broadband sends information in the form of an analog signal. Each transmission is assigned to a portion of the bandwidth, hence multiple transmissions are possible at the same time. Broadband communication is unidirectional, so in order to send and receive, two pathways are needed. This can be accomplished either by assigning a frequency for sending and assigning a frequency for receiving along the same cable or by using two cables, one for sending and one for receiving. In broadband frequency-division multiplexing is possible
What is the frequency of RC cars?
the most common are 27 megahertz which have colored crystals to tell your channel and spectrum which is a system of jumping frequency and are virtually interference free. everythings goin 2.4 and spectrum both basicly the same spectrum does not jump frequency it binds to the receiver of what ever you have and will only communacate with that one, for example you can have 1000 r/c cars or planes opperating at the same time and there will be no interferance.

Are gsm use sfh to improve signal?
Frequency Hopping is an old technique introduced firstly in military transmission system to ensure the secrecy of communications and combat jamming. Frequency Hopping is mechanism in which the system changes the frequency (uplink and downlink) during transmission at regular intervals. It allows the RF channel used for signaling channel (SDCCH) timeslot or traffic channel (TCH) timeslots, to change frequency every TDMA frame (4.615 ms). The frequency is changed on a per burst basis, which means that all the bits in a burst are transmitted in the same frequency.
How are digital images transmitted?
Digital images are transmitted on computer networks by first compressing them to reduce their size. JPEGs are an example of compressed image files.
Will the new digital signals be in both UHF and VHF?
Digital TV signals are transmitted on VHF starting on channel 2 and ending at the top of the UHF spectrum channel 69. At one time the plan was not to use the VHF band but it didn't work out that way.
