What do you mean 50 percent modulation index?
A(m)/A(c)=0.5 is known as 50% modulation index. where, A(m)=amplitude of message signal A(c)=amplitude of carrier signal
What is that full form of AM?
AM: amplitude modulation
What abbreviation am stands for?
Americum; Amplitude Modulation; Ante Meridiem...
What are examples of analogies?
It is a way to see differentences between items. Like: Cow is to barn as elephant is to zoo.
What is the acronym of AM?
AM is already an acronym for "amplitude modulation", a system where a radio wave carries a signal by varying the amplitude of the wave. It is opposed to FM or "frequency modulation" where the signal is carried by variations in the wave's frequency. AM should not be confused with the acronym am which stands for "ante meridionem", a Latin phrase meaning "before noon".
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.

What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.
What do you mean 50 percent modulation index?
A(m)/A(c)=0.5 is known as 50% modulation index. where, A(m)=amplitude of message signal A(c)=amplitude of carrier signal
Multiple choice question answer of AM modulation?
amplitude modulation is where we modulate our signal with a carrier signal amplitude changes but frequency remains constant in amplitude modulation
What are the advantages frequency modulation amplitude modulation?
Frequency modulation have some advantages over amplitude modulation, FM is not sensitive to the amplitude noise, and have high efficient use of transmitted power
Amplitude modulation and frequency modulation range in India?
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
Why is percentage modulation less than 100 percent in amplitude modulation?
The operator and transmitter engineer control the modulation level. It can be adjusted so that audio peaks produce 100% modulation, or less than 100%, or more than 100%. More than 100% produces audio distortion in the receiver, and it also 'splatters' across a wider part of the AM dial then it should. It sounds terrible on the radio, and it potentially interferes with other stations.
What is the range of modulation index in am?
The range of modulation index in amplitude modulation (AM) is typically between 0 and 1. A modulation index of 0 indicates no modulation, while a modulation index of 1 represents full modulation where the carrier signal amplitude varies from zero to peak value.
What is the highest modulation coefficient and percent modulation possible with a conventional AM system without causing excessive distortion?
the highest modulation coefficient is one (1) and percent modulation is 100
What is amplitude modulation?
Amplitude modulation is a method of sending information by modifying the intensity of a carrier wave.
