Why is the single sideband suppressed carrier version of amplitude modulation is not used for the sound broadcasting and television broadcasting?

A single sideband receiver have a BFO (Beat Frequency Isolator) that is generating the other half side of the original audio. The BFO is hand tuned to clarify the audio to, as close as possible to the original sound. An automatic clarifier is not really possible therefore music and voices never sound the same as the original.

Why amplitude modulation is used for video transmission?
IF we use frequency modulation for transmitting video signal this can cause phase shifting .and eyes can percieve this distortion effect easly . and requires more bandwidth to send the signal .Color levels are adjusted by amplitude in TV .So it s more logic to use Amplitude modulation .
Amplitude modulation and frequency modulation range in India?
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
What is the difference between the AM modulation and ASK modulation?
This is hard to explain. AM means amplitude modulation, while ASK is amplitude-shift keying. AM is usually analog as it is modulated based on the strength of the signal, though you can use it to send a digital signal. ASK represents digital data as variations in the amplitude of a carrier wave. Any digital modulation technique will represent the data using a finite number of different signals. While AM is used mostly for radio and television, ASK is used for telegraph signals, transmission across telecommunications equipment, and fiber optics.
Why the carrier for the amplitude modulation must be a sinusoidal waveform?
The wave in amplitude modulation must be a sine wave. A sine wave represents smooth repetitive oscillation, which is necessary for this process.
Sound quality between AM and FM?
There are two types of modulations. They are amplitude modulation and frequency modulation. In AM, amplitude of the signal is modified. In FM, frequency is getting modulated. Frequency modulated with carrier waves are transmitted and received by receivers without any distortion.
What is AM broadcasting?
amplitude modulation
What is AM radio broadcasting?
amplitude modulation
What is the practical uses of amplitude modulation?
radio broadcasting
Which modulation scheme requires the least minimum bandwidth?
Suppressed carrier single sideband amplitude modulation - SCSSBAM.
What are the two types of wave communication used in broadcasting?
AM and FM AM=Amplitude Modulation FM=Frequency Modulation Hope this helps
What has the author W I Manson written?
W. I. Manson has written: 'Amplitude modulation radio broadcasting'
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)

What is the meaning of suppressed carrier in am?
radio an amplitude-modulated wave in which only the sidebands are transmitted, the carrier being removedhttp://dictionary.reference.com/browse/suppressed+carrier+modulation
What is the full form of AM regarding radio broadcasting?
Aptitude Modulation means the height of the information changes the height of the signal in the radio frequency wave.
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 does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
