3. If its broken you have to replace it.
to amplify a small signal to sufficient level,so that it can travel to a large distance from first stage till the last stage
in DSB-SC since carrier is suppressed,hence power consumption is reduced and nominal.The power in the modulated signal is contained in all four sidebands.The bandwidth of the DSB-SC signal is double that of the message signal, that is, BWDSB-SC =2B (Hz).How many sidebands? There's only two; upper and lower.
i have no signal on my phone i have signal on my phone i have no signal on my television i have signal on m y television the signal has been interupted i dont know the hand signal i need to know the signal what is the signal strength teach me the hand signals what is the signal for danger i have little signal i have high signal i have no signal how much signal do i have how do i tell how much signal i have is there a sign for signal by the way you already put it in a sentence by asking a question lol
the signal can be converted into digital form and can be stored for further reference.display of the data is possible on a CRO.reading of analog data with the help of electrical transducers has less losses involved as compared to mechanical transducers.
Digital signal processing is the best compared to analog signal. It is because the digital signal is moreefficienterror freeimmune to noisethan an analog signal
a smoke signal can help people spot you in the woods.
The smoke signal was invented in 1785 as it was a good way of communicating without other people knowing what you are doing.
you may loose signal when typing .
Indians used smoke to communicate from a distance.

The Production Budget for Smoke Signals was $2,000,000.
2 buoyant smoke signals

A joint is a herbal cannabis that you can smoke
The boys looked for their own smoke to signal the ship but it had gone out.
Disadvantages are, because of cars giving off exhaust smoke. Advantages are, cellphones in case of emergencies.
Yes. Since the signal is beamed from space, anything in the path of it, even smoke/heavy cloud cover, can cause interference.
