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.

Analog is when audio or video is taken and translated into electronic pulses. Digital modulation is when audio or video is broken into binary codes and then transferred to the viewing device.

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 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).


Difference between delta modulation and differential pulse code modulation?

Delta modulation is not a type of quality conversion and runs on digital-to-analog, analog-to-digital. Differential pulse code modulation has a higher quality of conversion and runs on a 1-bit data stream.


What is the difference between pulse code modulation and delta modulation?

The difference between pulse code modulation and delta modulation is that pulse code modulation is a method of encoding audio information digitally while delta modulation is a method that converts analog to digital signal.


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 analog-digital hybrid modulation?

—Analog digital hybrid modulation seeks the ways to eliminate the incoherent quantization noise component in digital communication, instead of conveniently making it minimal.


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.
