The aim of digital modulation is to transfer a digital bit stream over an analog bandpass channel, for example over the public switched telephone network (where a filter limits the frequency range to between 300 and 3400 Hz) or a limited radio frequency band.

How to Generate digital data for bpsk modulation?
How to Generate digital data for bpsk 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.
Which modulation scheme requires the least minimum bandwidth?
Suppressed carrier single sideband amplitude modulation - SCSSBAM.
Difference between analog modulation and digital modulation?
Analog Pulse modulation is discreet in time but the formation is transmitted in continuous form. In digital pulse modulation, not only the time axis is discreet but the information is also in digital form. Examples of Analog PM are PAM and PTM i.e pulse amplitude and pulse time modulations respectively. Examples of Digital PM are PCM and PDM i.e pulse code and pulse delta modulations respectively.
Am single-sideband full carrier?
single sideband full carrier
Advantages of hybrid modulation over digital modulation?
presentation of analog digital hybrid modulation
Need of demodulation?
Demodulation is needed with modulation becoz modulation it is converting analog to digital signal n we can't understand digital. That's why we require digital to analog converter or demodulator.
Which analog modulation scheme requires minimum transmitted power and minimum channel bandwidth?
ssb modulation scheme
What are the Advantage of digital modulation over analog modulation?
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

What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.

GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
Which modulation scheme requires the least minimum bandwidth?
Suppressed carrier single sideband amplitude modulation - SCSSBAM.
Difference between digital transmission and digital modulation?
The Difference of two is only first digital has a transmission and second digital has modulation.....thats all....i think that's too clear ha...
What is the unit for modulation index?
Modulation index is also called as Modulation depth. The modulation index of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level.
What has the author Gordon Drury written?
Gordon Drury has written: 'Coding and modulation for digital television' -- subject(s): Digital modulation, Multiplexing, Digital television, Coding theory
