Which modulation technique is most prone to noise PWM or AM?
AM = Amplitude Modulation and is more prone to noise because the signal amplitude caries the intellegence, Noise changes this easily. PWM is Pulse Width Modulation and noise does not change the width of the pulses, though it may introduce other pulses. Therefore the original intellegence is still recoverable.
What is the impedance of water?
Impedance of water is the density of water times the sound velocity in water ANSWER: Pure water has a high resistivity. An ohmmeter i a good way to check for quality of water. If resistance is low it means that it is has other material floating in there.
Compare high level modulation and low level modulation?
IN LOW LEVEL MODULATION THE MODULATING SIGNAL IS APPLIED NEARER THE CARRIER OSCILLATOR N IN HGH LEVEL MODULATION MODULATING SIGNAL IS APPLIED AT OUTPUT OF FINAL POWER AMPLIFIER OR FAR FROM CARRIER OSCILLATOR... IN OTHER WORDS :::: IN HAIGH LEVEL MODULATION THE AF SIGNAL IS APPLIED TO COLLECTOR OR PLATE AS THEIR RESPECTIVE DEVICES..... N IN LOW LEVEL MODULATION AF SIGNAL IS APPLIED AT BASE OR GRID IN TRANSISTOR AND TUBES RESPECTIVILY IN LOW LEVEL MODULATION THE MODULATING SIGNAL IS APPLIED NEARER THE CARRIER OSCILLATOR N IN HGH LEVEL MODULATION MODULATING SIGNAL IS APPLIED AT OUTPUT OF FINAL POWER AMPLIFIER OR FAR FROM CARRIER OSCILLATOR... IN OTHER WORDS :::: IN HAIGH LEVEL MODULATION THE AF SIGNAL IS APPLIED TO COLLECTOR OR PLATE AS THEIR RESPECTIVE DEVICES..... N IN LOW LEVEL MODULATION AF SIGNAL IS APPLIED AT BASE OR GRID IN TRANSISTOR AND TUBES RESPECTIVILY
How many channels has 2MB PCMpulse code modulation?
Total 32 channels out of which 30 for voice 1 for signalling and other for Syncronization
The total power content of an AM signal is 1000W Determine the power being transmitted at the carrier frequency and at each of the sidebands when the percent modulation is 100 percent?
In Double Sideband AM (DSB-AM) modulation, two thirds of the power is consumed by the carrier, so 667W would be transmitted at the carrier frequency. The remaining 333W is split equally between the two sidebands, each being mirror images of each other.
Explain how distance time and velocity are related to each other?
They are related through the formula distance = time x velocity (assuming constant velocity).
What is the difference between voice modulation and intonation?
Voice modulation refers to changes in pitch, volume, and pace while speaking to convey different emotions or meanings. Intonation, on the other hand, refers to the rising and falling patterns of pitch within a sentence or phrase that can indicate a question, statement, or emphasis on certain words. In essence, voice modulation encompasses a range of changes in the voice, while intonation specifically focuses on pitch patterns within speech.
Is velocity and energy related?
Any object that has velocity has a type of energy known as kinetic energy - i.e., energy of movement. However, there are other types of energy that are not directly related to velocity.
How are mass and density related to each other?
mass = volume x density
How do salinity and density related to each other?
Increasing the salinity the density is also increased.
How are mass volume and density related to each other?
mass = volume x density
How are acceleration and velocity alike and different from each other?
-- both are related to measurements of motion of objects -- acceleration is the rate at which velocity changes
What is the meaning of FM in FM Radio?
FM means frequency modulation AM means amplitude modulation
What is Modulation index in Frequency modulation?
Modulation Index is the ratio of the maximum deviation frequency to the frequency of modulation. In other words it is the ratio of the spread in frequency spectrum to the frequency that was used to modulate the carrier. For FM, modulation index is given by the formula mf= df/f where, mf=modulation index for FM df=difference in carrier frequency f=frequency of the signal
Is Armstrong method for FM generation and armstrong phase modulator same?
Since we can generate fm from phase modulation, thus both are related to each other
What does population density means in biology?
Nothing is strictly related between population density and biology. Population density is linked to other factors. This is a statistical demographics issue..
What do the letters FM on your radio stand for?
They could mean a lot of things, but in the context of each other they probably stand for Amplitude Modulation and Frequency Modulation (two different methods for sending an audio signal using radio waves) respectively.
