PPM=Pulse Position Modulation is suited for data communications via optical fiber or short distance line-of-sight
as in radio control models. A pulse is encoded by placing it in a specific position in time. Proper sync is
required and transmission distortion can render it useless.
FM=Frequency Modulation which is more suited for audio communications as in broadcast radio or personal
communicators. The modulation of a carrier is accomplished by causing the frequency of the carrier to vary as a
function of the audio. The speed of the variation is the frequency of the audio and the amount of the variation is
the amplitude of the audio.

How many ml in 100 ppm?
In one Liter, there are 1000 milliliters. Ppm stands for parts per million. Ppm tells you the concentration of some liquid or gas in a solution. If there are 100 parts out of a million of CO2 (100 ppm), that is equal to 100/1,000,000, which means that .01% of the molecules in the mixture are CO2. mL and ppm are two different units of measurement. One represents distance and the other represents concentrations of fluids.
What is the abbreviation for frequency modulation?
" FM " is.
What do the acronyms ppb and ppm represent?
PPB stands for parts per billion and is used to measure the concentration of a substance in a mixture. PPM stands for parts per million, and is another unit of measurement like ppb, but represents a higher concentration in a mixture.
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.
What wave has a shorter wavelength AM or FM?
Generally, the wavelength of an FM signal is shorter than an AM signal. A typical FM broadcast band is 88-108 MHz, while a typical AM broadcast band is 540-1660 KHz, making the FM signal wavelength 100 times shorter.
Why noice level less in FM than am?
Frequency modulation differs from amplitude modulation. FM coverage distance is less with more clarity due to non interference with carrier waves.
Is 100 ppm better or worse then 50 ppm?
100 ppm is worse than 50 ppm. The higher the ppm value, the more concentrated the substance is in the solution. In this case, a concentration of 100 ppm is twice as much as 50 ppm.
How you write ppm capital or small?
ppm
What are the critical limits of micro-nutrients in soil?
Zn < O.6 ppm Fe < 4.5 ppm Mn < 2.0 ppm Cu < 0.2 ppm
What percent is 115 ppm in water?
115 ppm is 0.0115%.
What is 0.110 ppm as a percent?
0.110 ppm = 0.000011%
How do you convert 0.5mM to ppm?
0.5Mm = 50 PPM
What is 46 ppm in percent?
46 ppm is 0.0046%
How do you convert to ppm to percentage?
Multiply ppm by 10000.
How do you covert from 5 ppm to percent?
ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.
How do I convert a .06 percent selenium to 90ppm?
1 percent is 10,000 ppm .06 percent = (.06 x 10,000) = 600 ppm 90 ppm = (90 / 10,000) = 0.009 percent 0.06 percent is not the same thing as 90 ppm. This is not a math problem. You have to change the material. That's a chemistry problem.
Convert 322.000 ppm to percent?
322 ppm = 0.0322%
