When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.
What is gfsk modulation?
whatbis GMSK MODULATION ?
What is collector modulation?
Collector modulation is the amplitude modulation in which modulator varies the collector voltage of a transistor.
Define modulation and modulation index?
a measure of the degree of frequency modulation expressed numerically for a pure tone modulation as the ratio of the frequency deviation to the frequency of the modulating signal.
What is square law diode modulator?
Methods of amplitude modulation can be put in the two categories namely Linear modulation methods and Square law modulation methods. Linear modulation method utilizes the linear region of the current voltage characteristics of the amplifying device that is transistor or electron tube. Square law modulation method utilizes the square law region of some current voltage characteristics of a diode or transistor or electron tube. A large number of linear modulation methods have been devised and have been used to varying degree. These methods are namely linear shunt plate modulation or anode choke modulation, linear series plate modulation, grid bias modulation, cathode modulation, suppressor grid modulation, screen grid modulation, collector modulation. Square law modulation circuits make use of non linear current voltage characteristics of diodes or triodes and are in general suited for use at low voltages. Important square law modulation methods are square law diode modulation and balanced modulator.
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
Need for modulation?
modulation
What are the two types of angle modulation?
Frequency Modulation and Phase Modulation
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
How velocity modulation and density modulation related to each other?
due to velocity modulation density modulation occurs in TWT
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
Why frequency modulation and phase modulation are called angle modulation?
i dont know ans. of this.
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.
