How many sidebands? There's only two; upper and lower.
Frequency modulation have some advantages over amplitude modulation, FM is not sensitive to the amplitude noise, and have high efficient use of transmitted power
presentation of analog digital hybrid modulation
The feature of the multiplier module's output that suggests it is essentially a Double Sideband Suppressed Carrier (DSBSC) signal is the absence of a carrier frequency component in the output spectrum. In DSBSC modulation, the carrier wave is suppressed, and the output consists of two sidebands that carry the modulating information. This characteristic can be identified by analyzing the frequency domain representation, where only the upper and lower sidebands are present without the carrier frequency peak.
ADVANTAGES OF IDS
To send the information or message at the large distance as you can.
1)digital modulation can easily detect and correct the noise. where as analog modulation has little complexity 2)security is more in digital modulation 3)digital modulated signal can traverse a long distance compared to analog modulation
Advantages: it improves frequency stability. phase modulation n demodulation is easy as compared to frequency modulation.
BW=2 fm
what are the advantages of amplitude modulation over frequency modulation?
The delta modulation transmits only one bit for one sample. Thus the signaling rate and transmission channel bandwidth is quite small for delta modulation. The transmitter and receiver implementation is very much simple for delta modulation. There is no analog to digital converter involved in delta modulation. The disadvantages of delta modulation are slope overload distortion and granular noise. These are the two drawbacks of delta modulation.
carry information as well as to generate other pulse modulations.
Pulse position modulation offers high noise immunity, efficient use of bandwidth, and easy implementation with digital circuits. This modulation technique is particularly useful in applications requiring high data transmission rates and reliable communication in noisy environments.
