- 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.
What else can I help you with?
When modulation frequency is doubled modulation index also doubled in case of FM or pm or am?
In Frequency Modulation (FM), if the modulation frequency is doubled, the modulation index does not necessarily double; it depends on the amplitude of the modulating signal. In Amplitude Modulation (AM), the modulation index is defined as the ratio of the peak amplitude of the modulating signal to the carrier amplitude, so it remains unchanged with varying modulation frequency. For Phase Modulation (PM), similar to FM, the modulation index is influenced by the amplitude of the modulating signal and does not inherently double with the modulation frequency. Thus, modulation frequency and modulation index are not directly linked in this way for FM, PM, or AM.
When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.

What are the disadvantages of delta?
The disadvantages of delta modulation are slope overload distortion and granular noise.
Disadvantages of DSB-SC modulation?
-Carrier not available in receiver -Envelope detection not possible
What are Advantages of delta 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.
Advantages and disadvantages of envelope detection amplitude modulation compare to synchronous am detection?

What are the advantages and disadvantages of RC phase shift oscillator?
Advantages: it improves frequency stability. phase modulation n demodulation is easy as compared to frequency modulation.
What are Disadvantages of Adaptive delta modulation?
There are two major disadvantages of delta modulation: 1. Slope overload distortion: occurs when modulating signal varies faster than counter recovered signal. 2. Granular noise: occurs when variation in modulating signal is smaller than step size.
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
Need for modulation?

What are the two types of angle modulation?
Frequency Modulation and Phase Modulation
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
How velocity modulation and density modulation related to each other?
due to velocity modulation density modulation occurs in TWT
What are the advantages and disadvantages of phase modulation?
Advantage - 1. Phase modulation & demodulation is easy compared to Frequency modulation. 2. Phase modulator is used in determining velocity of moving target by extracting Doppler information. Doppler information needs stable carrier which is possible in phase modulation but not in frequency modulation. Disadvantage - 1. Phase ambiguity comes if we exceed its modulation index pi radian(180 degree). 2. we need frequency multiplier to increase phase modulation index. Visit my website http://harshit.org
