Which pulse modulation scheme is used as an intermediate step in the creation of PCM?
The pulse amplitude modulation (PAM) scheme is used as an intermediate step in the creation of pulse code modulation (PCM). In PAM, the amplitude of discrete pulses represents the sampled values of the analog signal. These amplitude levels are then quantized and encoded into a binary format to produce the final PCM signal. This process enables the efficient digital representation of analog information for transmission and storage.

What is ppm modulation?
pulse position modulation, used in many RC model aircraft controls.
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.
How regenerative repeater work in pulse code modulation?
Regenerative Repeater is used for the PCM (Pulse code modulation ) it amplifies the signal because the effect of the channel over the signal .
What type of modulation produces pulses whose duration is proportional to the amplitude of the intelligence signal?
Pulse-Amplitude Modulation
How do you differentiate FM from PM signal?
A: FM means frequency Modulation meaning the frequency remain the same. pulse modulation the frequency can vary
What type of modulation is pulse position modulation and why?
It is a type of Pulse modulation as in PPM the position of pulse of carrier pulse train is varied in accordance with the modulating signal.
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.
Explain with diagram the technique Pulse-amplitude modulation?
Explain with diagram the technique Pulse-width modulation?
What are the three types of pulse modulation?
Actually there are four:widthamplitudepositioncodeOf these four pulse code modulation is digital while the other three are analog.
What is the difference between space vector modulation and pulse width modulation?
There is no difference.
What do you mean by pulse width modulation?
pulse width modulation is nothing but changing on and off time period of a waveform without changing its frequency
WHICH IS BEtter Flat top or natural top pulse amplitude modulation?
For the generation of a PAM signal we use a flat top type PAM scheme because during the transmission,the noise is interfered at top of the transmission pulse which can be easily removed if the PAM pulse in flat top
