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.
What is the usage of frequency?
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.
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.
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
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
What does AM and FM mean?
am is amplitude modulation, fm, frequency modulation
Why is amplitude modulation susceptible to noise but not frequency modulation?
because noise usually changes the amplitude not frequency.
