Analog modulation
In analog modulation, the modulation is applied continuously in response to the analog information signal.
Common analog modulation techniques are:
- Amplitude modulation (AM) (here the amplitude of the modulated signal is varied)
- Double-sideband modulation (DSB)
- Double-sideband modulation with unsuppressed carrier (DSB-WC) (used on the AM radio broadcasting band)
- Double-sideband suppressed-carrier transmission (DSB-SC)
- Double-sideband reduced carrier transmission (DSB-RC)
- Single-sideband modulation (SSB, or SSB-AM),
- SSB with carrier (SSB-WC)
- SSB suppressed carrier modulation (SSB-SC)
- Vestigial sideband modulation (VSB, or VSB-AM)
- Quadrature amplitude modulation (QAM)
- Double-sideband modulation (DSB)
- Angle modulation
- Frequency modulation (FM) (here the frequency of the modulated signal is varied)
- Phase modulation (PM) (here the phase shift of the modulated signal is varied)

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.
What are the advantages 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

How is analog modulation different from digital modulation?
i refered modulation is the sequence of message in to analog symbol( Simon haykin ,communication systems),,but i am not clear with this,couul u pls clarify?
What is difference between ask and am?
The most fundamental difference, I would say, is that Amplitude Modulation (AM) is a kind of Analog Modulation Technique (the modulation is applied continuously in response to the analog information signal) where Amplitude Shift Keying is a type of Digital Modulation Technique ( an analog carrier signal is modulated by a discrete signal, digital modulation methods can be considered as digital-to-analog conversion, and the corresponding demodulation or detection as analog-to-digital conversion. The changes in the carrier signal are chosen from a finite number of M alternative symbols).
What is adaptive modulation?
Adaptive delta modulation is a analog-to-digital and digital-to-analog conversion technique which is primarily used for voice transmission data and can be used for multiple purposes.
