A: no idea because it can
You need to assess the frequency, amplitude and see if there is any distortion in the waveform. The best way is with an Oscilloscope.
It is a way to see differentences between items. Like: Cow is to barn as elephant is to zoo.
Comparing this figure of merit with the corresponding result described in Equation (2.1521 for an FM system, we see that the use of frequency modulation offers the possibility of improved noise performance over amplitude modulation when
A flashlight simply emits light. The light contains no information other than to provide light so people can see where they are going.
An oscilloscope is a device used to visualize sound waves as they are being produced. It displays the waveform of the sound signal graphically, allowing users to see the shape, frequency, and amplitude of the sound wave in real-time. This can be helpful for analyzing and troubleshooting audio signals in fields such as music production, acoustics, and telecommunications.
An oscilloscope is a machine that allows you to see sound waves. It displays the waveform of an electrical signal that represents the sound waves in real time.
None, exepct for a crazy hollogram imstument
A: xray emits from TV, OSCILLOSCOPE and some more instruments due to requirement of hi voltage to see the display
Amplitude modulation is where a constant carrier is modulated by the signal, so that the envelope of the carrier represents the signal. Frequency modulation is where a constant carrier is modulated by the signal, so that the frequency of the carrier represents the signal. Phase modulation is where a constant carrier is modulated by the signal, so that the phase angle of the carrier represents the carrier.
Your question is entirely too ambiguous. What made you think this? What was the reasoning for your choice of modulation technique? Example you said FM. Why? Not to be nasty but it appears to me you do not know what FM means. If you think it is the FM broadcast band OK but FM is Frequency Modulation. AM is the same but using Amplitude Modulation. There are many other forms of modulation and they can be used on any radio frequency you can generate. However there are laws requiring various techniques on certain frequency to keep form causing interference. FM does not mean anything about frequency. Most people think of FM as the FM radio broadcast. Nope FM is a method. So why did you think this? Was it due to your FM radio in the car? If so,,,,, you bet I could talk to you on it. I would however need to know the frequency you are tuned to. Or in another form "what station are you tuned to? See how ambiguous your question is?
You cant see sound, but you better can listen to it. An oscilloscope can show the microphone output.
Your question doesn't give enough detail. AM typically stands for amplitude modulation. It is how AM radio works. A constant frequency is transmitted and the amplitude is varied to modulate the carrier wave with an information signal such as a song. Hence if you were examining how an AM signal changed you would see changes in the peak-to-peak voltage of the carrier frequency waveform.
