Why values of modulation index greater than one are not used in full-carrier AM system?
If the modulation index is greater than 1 (more than 100% modulation) the modulated carrier signal is periodically reduced to zero. This does not effect the transmitter but at the receiver these "dead carrier" intervals result in dropouts in the audio stream from the loudspeaker producing a distorted output that is difficult to understand.

What is amplitude modulation derive expression for am wave and modulation index?
the maximum amplitude of carrier wave varied with respect to instantaneous values of message signal is called amplitude modulation
What do you mean by depth of modulation index?
The depth of modulation index refers to the extent to which a carrier signal is varied by a modulating signal in amplitude modulation (AM). It is typically expressed as a percentage and indicates how much the amplitude of the carrier wave changes in response to the modulating signal. A modulation index of 100% means full modulation, where the carrier's amplitude varies completely with the modulating signal. Values above 100% can lead to distortion and over-modulation, impacting the quality of the transmitted signal.

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 restrictions apply to the values that can be assigned to subscripts?
They have to be positive integers greater than or equal 0.
The values of amplitude modulation index is objective types?
The values of amplitude modulation index is categorized as an objective type.
What is amplitude modulation derive expression for am wave and modulation index?
the maximum amplitude of carrier wave varied with respect to instantaneous values of message signal is called amplitude modulation
Can a single modulation type be employed in such a way as to maximise data throughput at all viable values of SNR?
Yes, this is possible and can be done. The single modulation type can be employed in such a way as to maximize data throughput at all viable values of SNR.
Why the name pulse code modulation?
because the data is sent as a series of digitally coded numeric values.

what is greater 42.9 or 42.900?
They are identical values.
What is greater .75 or 0.750?
They are both the same values
What is the median of a set of values?
the median is a value of which half of all the values are less than, and half of all the values are greater than.
What is the system of values on mars?
Mars is not known to have any inhabitants, which are the ones that would have a "system of values".
How is the changing of values for an object through a system represented?
The changing of values for an object through a system is represented by tracking and displaying the different values as they are modified or updated within the system.
Is 12.1 greater that 12.10?
No because they are both of equal values
Is 2.7 greater than 2.70?
They have both the same values
