Why phase modulation is used?
Actually phase modulation was used for the color signal in all analog TV systems.Phase modulation, with some signal preprocessing, was used to indirectly get frequency modulation in many FM transmitters.Certain modems use phase amplitude modulation.etc.
How regenerative repeater work in pulse code modulation?
Regenerative Repeater is used for the PCM (Pulse code modulation ) it amplifies the signal because the effect of the channel over the signal .
Can laser beam be used as RF signal carrier?
When modulated with a radio frequency signal, they will indeed carry information. As in fibre-optic cables. The modulation may be of the several commonly used types, amplitude, frequency, phase ... modulation.
Modulation can be used to make a signal conform to a specific pathway?
yes of course
Why frequency modulation is superior to amplitude modulation?
FM provides noise immunity, whereas AM is easily affected by noise. With FM, the amplitude of the sound is converted into a shift in frequency. So the volume is limited by the bandwidth, but the frequency of the sound can vary as much as it likes, giving a higher fidelity sound. Spikes induced on the signal usually affect the amplitude of the signal. The amplitude of an FM signal is not used in the demodulation process and is therefore immune to spikes in the signal. AM was first used in radio because it is very easy to achieve using basic components. A single rectifier only, is needed to recover the audio. FM is quite a complicated process and could only be achieved once electronics had progressed.

What type of modulation is used to carry the picture portion of a television signal?
Amplitude Modulation (AM) is used for the picture portion of a television transmission while Frequency Modulation (FM) is used for the audio portion.

What is full form of FM?
Frequency ModulationFM broadcasting is a broadcast technology invented by Edwin Armstrong that used Frequency Modulation (FM) to provide high fidelity sound over broadcast radioFrequency Modulated and Amplitude Modulation :) The way a signal is transmitted.

What do understand by frequency modulation?
It means that there is a base wave, and that the frequency is changed to transmit a signal. For example, if you want to transmit a signal representing a 1000 Hz sound, the frequency of the base wave would be increased and decreased a thousand times in a second.
What is tone modulation?
Tone modulation through of modulating a carrier frequency using the charactoristics of a sound, its the method used for telephone
What is function of amplitude modulation?
Amplitude modulation (AM) is a method used in telecommunications to vary the strength (amplitude) of a carrier signal in proportion to the waveform being sent. This modulation technique allows the transmission of audio or data signals through changes in the amplitude of the carrier signal. AM is commonly used in broadcast radio to carry audio signals.
What is analog modulation?
Analog modulationIn analog modulation, the modulation is applied continuously in response to the analog information signal.Common analog modulation techniques are:Amplitude modulation (AM) (here the amplitude of the modulated signal is varied) Double-sideband modulation (DSB) Double-sideband modulation with unsuppressed carrier (DSB-WC) (used on the AM radio broadcasting band)Double-sideband suppressed-carrier transmission (DSB-SC)Double-sideband reduced carrier transmission (DSB-RC)Single-sideband modulation (SSB, or SSB-AM), SSB with carrier (SSB-WC)SSB suppressed carrier modulation (SSB-SC)Vestigial sideband modulation (VSB, or VSB-AM)Quadrature amplitude modulation (QAM)Angle modulation Frequency modulation (FM) (here the frequency of the modulated signal is varied)Phase modulation (PM) (here the phase shift of the modulated signal is varied)
