Which modulation technique is used in gsm?
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
What is the technical difference when it comes to the implementation of AM and FM?
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
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.
Which modulation technique is used in gsm?
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
How do you converion baud rate to symbol rate?
baud rate = symbol rate= modulation rate all the same thing
What is the difference between NRZ L and Manchester encoding?
For NRZ we require large bandwidth,because transition will not occur in middle of bit.whereas in Manhaster encoding transition will occur middle of the bit so Data rate = Modulation rate/2 Regards, Dilip Prajapati
Why there is half-rate and full-rate in GSM?

Calculate the bit rate for the given baud rate and type of modulation?

Given a baud rate of 1200 bauds per second and modulation technique what is the data?
all you need is to know the modulation technique and then you can know how many bits per one symbole then to calculate the data rate = baud rate * bits/symbole
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.
How can the modulation rate of the laser diode be increased?
the basic limitation on direct modulation rate of laser diodes depend on the spontaneous emission stimulated emission carrier life time. and these limitation can be taken care by semiconductor band gap and the carrier concentration.
What determines the data rate that a modem can support?
The bandwidth of the transmission media The modulation encoding used
What bit rate are peugoet immobilizer codes sent at?
i need to know what baud rate or pulse width modulation duration immobilizer codes are sent at
What are the Uses of modulation techniques in telecommunication?
In GSM generally GMSK which is a derivative of MSK is beeing used because of its spectral efficiency and more noise resistant. Regards Sumeer Mehaboob
What is meant by repetition rate of the AM envelope?
The repetition rate of the amplitude modulation (AM) envelope refers to how often the modulation waveform repeats within a given unit of time. It indicates the frequency at which the carrier signal is modulated by the audio signal in an AM transmission. A higher repetition rate results in a faster fluctuation in the amplitude of the carrier signal.
