In amplitude modulation, modulation depth refers to the ratio of the unmodulated carrier amplitude to the amplitude deviation for which the modulated carrier wave reaches its minimum value. If this minimum value is zero, the modulation depth is 100%.
For amplitude modulation,modulation depth = (a-b)/(a+b),
wherea is the unmodulated carrier amplitude, and
b is the minimum amplitude deviation.
The modulation depth ratio is also referred to as the modulation index.

What does am and fm?
fm- frequency modulated am- amplitude modulated
What does a m mean in radio language?
AM = amplitude modulated. FM = frequency modulated.
What is depth of modulation?
In amplitude modulation, modulation depth refers to the ratio of the unmodulated carrier amplitude to the amplitude deviation for which the modulated carrier wave reaches its minimum value. If this minimum value is zero, the modulation depth is 100%.For amplitude modulation,modulation depth = (a-b)/(a+b),wherea is the unmodulated carrier amplitude, andb is the minimum amplitude deviation.The modulation depth ratio is also referred to as the modulation index.
A two cavity klystron tube is a?

What is FM means frequency modulated or fast modulated?
FM means Frequency Modulation.
When a carrier is phase modulated with an integrated modulating signal the resultant is?
It gives frequency modulated signal
What does AM and FM mean?
am is amplitude modulation, fm, frequency modulation
Why analog data have to be modulated onto an analog signal?
For transmission through a radiowave.
An AM radio signal is?
amplitude modulated
How many syllables are there in the word modulated?
4
Are digital transmissions modulated over a carrier?
yes for transmission of the signal to take place smoothly,digital tranmission needs to be modulated over a carrier
What is the unit for modulation index?
Modulation index is also called as Modulation depth. The modulation index of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level.
