How do you calculate upper and lower sideband frequencies?
fc+fm and fc-fm
What causes sideband frequency?
If you subtract from the carrier frequency the frequency of the tone that modulates it, then filter out the carrier frequency, then you have a lower sideband frequency. If you add to the carrier frequency, filter out the carrier, then you have an upper sideband frequency.
What is the dynamic characteristic of a double-sideband?
Double-sideband modulation is a type of amplitude modulation where both upper and lower sidebands are present with the carrier signal. The dynamic characteristic of double-sideband modulation is that it allows for efficient use of bandwidth but is susceptible to fading and interference.
What is the difference in the usefulness of upper-sideband and lower sideband transmission?
There's no difference in their usefulness, and no basis for any preference on the part of the transmitting party. There's an advantage to the receiving party, however, if he can coordinate with the transmitting party. The advantage of having a choice is that you can choose whichever mode encounters less interference, and you can switch 'on the fly' if the congestion/interference environment changes. Upper sideband may be somewhat more difficult to receive clearly. This isn't a technical issue, though. It's just sometimes harder for the operator behind the tuning knob to tune it clearly, and slightly-mistuned upper sideband is harder to understand than slightly-mistuned lower sideband is, because the frequencies in the voice are inverted relative to each other.
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.
How do you calculate frequency range of double side band modulated signal?
Upper sideband = Carrier frequency + modulating frequencyLower sideband = Carrier frequency - modulating frequency
What is the definition to box and whisker plot?
A data display that organizes data values into four parts using the lower extreme,lower quartile,median,upper quartile,and upper extreme.
What is mean by full carrier?
At this point we're talking about amplitude modulation. If you're transmitting with "29.000" MHz displaying on your radio's frequency display and your bandwidth is set to 4 kHz, you are transmitting useful intelligence from 28.996MHz to 29.004MHz--4KHz on each side of the carrier--in "full carrier" or "double sideband" mode. You wouldn't actually transmit this for a couple of reasons. The most important reason is that using filters in your radio to remove either the signal below 29MHz (called "upper sideband" or USB operation) or the signal above it (called "lower sideband" or LSB) allows another operator to use the piece of spectrum you relinquished. The other advantage is SSB makes more efficient use of your amplifier, so you can talk to people farther away from you and they can hear you better. So..."full carrier" means double sideband, and then there's single sideband.
When you do modulation in time domain you get modulated waveform of modulating signal information and carrier. How can you recognize the upper and lower side bands in time domain modulated waveform?
You need modulation signal(carrier) which is a required signal in order to make envelope of time domained signal(target signal). The modulating signal is imposed on modulation signal.This creates envelope of waveform which is modulated(desired) signal. Now, the desired signals uper and lower sideband of signal strictly depends on modulation signal's bandwidth. Max. peak of that signal is uper sideband and min. peak is lower sideband for this modulated signal.
What is SSB radio?
'SSB' stands for "single sideband modulation".
What is meant by the analytical working range of an instrument?
Each instrument used in analytical chemistry has a useful working range. This is the range of concentration (or mass) that can be adequately determined by the instrument, where the instrument provides a useful signal that can be related to the concentration of the analyte .All instruments have an upper and a lower working limit. Concentrations below the working limit do not provide enough signal to be useful, and concentrations above the working limit provide too much signal to be useful. When calibrating an instrument for use, the experimenter must be familiar with both the lower and upper working range of the chosen instrument.
