- 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.

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 is gfsk modulation?
whatbis GMSK MODULATION ?
What is collector modulation?
Collector modulation is the amplitude modulation in which modulator varies the collector voltage of a transistor.
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?
ADVANTAGES OF IDS
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?
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 is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
