Why values of modulation index greater than one are not used in full-carrier AM system?
Wiki User
∙ 16y ago
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 is a system of values?

What restrictions apply to the values that can be assigned to subscripts?
They have to be positive integers greater than or equal 0.
What type of operator is used to compare two values?
Conditional operators are used to compare two values. The result of a comparison is either true or false. Boolean data types can hold the values true or false. Here's a list of operators. = Equal to > Greater than < Less than >= Grater than or equal to <= Less than or equal to <> Not equal to
The changing of values for an object through a system is represented by the?

The values of amplitude modulation index is objective types?
The values of amplitude modulation index is categorized as an objective type.

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.
Can information system aid in achieving shared values?
Yes it can and this forum called Wiki-Answers is actually making that idea possible by providing a social network of shared ideas and values. There would be some resistance to change and compromise for the greater good but as long as there are a few people who choose to work for the greater good then it is possible to achieve that goal of harmonizing our world with shared values of justice and equity.
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".
What is greater 10.30 or 10.3?
They both have equal values
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
