What else can I help you with?
What will happen if frequency of modulating signal is greater than the carrier signal in amplitude modulation?
Then the signal will be the same amplitude.
When signal amplitude is equal to carrier amplitude then modulation index is?
amplitude modulating signal
Why is amplitude modulation susceptible to noise but not frequency modulation?
because noise usually changes the amplitude not frequency.
What is signal modulation?
modulating signal is the message to be carried by the carrier signal.
What is the technical difference when it comes to the implementation of AM and FM?
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
What is the usage of frequency modulation?
It is a device or electronic circuit that changes the frequency of an oscillator according to the amplitude of modulating signal. For instance, if the modulation is linear, the modulator changes the frequency proportional to the amplitude of the modulating voltage.
In FM does the amplitude remains constant?
In frequency modulation (FM) the amplitude does not remain constant. Instead, the amplitude varies according to the modulation index and the frequency of the modulating signal. This is in contrast to amplitude modulation (AM), where the amplitude of the carrier signal is modulated while the frequency remains constant.
What will happen if frequency of modulating signal is greater than the carrier signal in amplitude modulation?
Then the signal will be the same amplitude.
Why you go for modulation?
modulating signal is the low frequency signal .so we cant transmit for a long distance.so we go for modulating the signal either by modulating the amplitude or frequency or phase of the signal.
What is Modulation index formula in Frequency modulation?
The modulation index formula in frequency modulation (FM) is given by the equation: β = Δf / fm, where β is the modulation index, Δf is the peak frequency deviation, and fm is the modulating frequency. Modulation index indicates how much the carrier frequency is being varied by the modulating signal in FM.
In phase modulation the amount of phase shift in the carrier signal depends on the of the modulating signal and the rate of phase shift depends on the of the modulating signal?
Amplitude Frequency
Is it true that information can be carried on a carrier wave by changing or modulating either the amplitude or frequency?
in frequency modulation, frequency of carrier signal changes. so frequency variations of carrier convey all the information in frequency modulation.
When signal amplitude is equal to carrier amplitude then modulation index is?
amplitude modulating signal
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
What are three frequency components of an am wave?
The three frequency components of an amplitude modulation (AM) wave are the carrier frequency, the upper sideband frequency (carrier frequency + modulating frequency), and the lower sideband frequency (carrier frequency - modulating frequency). These components are responsible for carrying the signal information in an AM wave.
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
Amplitude modulation and frequency modulation range in India?
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
