Which of the three multiplexing techniques arre used to combine digital signals?

Frequency-division multiplexing, wavelength-division multiplexing, and time-division multiplexing.


How you can mix the laser light of high frequency by dichroic mirror?

Will not happen in free space. Phononicaly in a crystal you can mix light. No where else. Light beams crossing each other will not effect each other or combine. A mirror will not combine them either.( This may not be true in extreme lab conditions and new metamaterials. )


How the combine harvester works?

The combine harvester works by cutting and separating the crops. The combine is probably on of the most dangerous pieces of farm equipment. There are many document cases of maiming involving the combine.


What year was the combine invented?

The Combine Harvester was invented in 1834 by Hiram Moore


What is the difference between heterodyning and superheterodyning?

When you combine signals of the same or different frequencies. The resulting energy will be each original frequency and the sum of the frequencies and a frequency that is the difference of the two signals. This is the basis of heterodyning. This allows us to take an information signal and "upconvert" it to the RF realm for transmission. But the same processes can be used to "downconvert" or to beat one signal against the other to get a lower frequency representation of the energy. After hererodyning came out, newer radios were sold as superheterodyning as a marketing ploy. Sorry, but it is not more complex than that. This was back in the early 20th century and the idea of fair marketing or truthful processes were not legal issues like today. Have a nice day. Bob

What are the parts of a Doppler Radar?

Same as the "regular" radar, except that the receiver is a bit different. In regular radar, the receiver looks for the returning signal on the frequency the transmitted pulse was sent out. Yes, it sees" Doppler shifted signals, but with decreasing sensitivity. And it does little with them but combine them with the signal on the frequency of the transmitted pulse. With Doppler radar, the receiver looks for a "band" or group of frequencies around the frequency at which the transmitted pulse was sent out. These "nearby" frequencies represent returns from materials or substances that are moving relative to the transmitter (toward or away from it). And the receiver works with a microprocessor based "analyzer" to paint a picture based on those returning signals that are near the frequency of the transmitted signal and not right on it. Basically, radar has a transmitter, the waveguide to the antenna, the antenna itself, and the receiver. The receiver is plumbed into the same waveguide the transmitter is connected to, but there is a junction (like a "T") where the transmitter and receiver are connected that is capable of directing the transmitted signal out along the waveguide and keeping it from going into the receiver, and then allowing the returned signal to get to the receiver without being "lost" by going back into the transmitter. There is a control system and a display system associated with the equipment as well. Just as one might expect.

How do overtones create a rich and complex sound in musical instruments?

Overtones are higher frequency vibrations that occur along with the fundamental frequency of a musical note. These overtones combine with the fundamental frequency to create a rich and complex sound in musical instruments. The presence and interaction of these overtones give each instrument its unique timbre or tone quality.


Do the voyager class constructicon transformer 2 rotf toys combine into devestator?

No they do not. Devastator can be done one of two ways. Buy the smaller size characters Buy the stand alone Devastator (with no alt modes)


Which zords are joining to make valvemax megazord?

Ranger Green's Tail Spinner, Ranger Black's Wolf Cruiser and the automated Croc Carrier are the 3 zords that combine together to form the Valvemax Megazord.


What has a higher frequency than the fundamental frequency?

The fundamental = 1st harmonic is not an overtone!Fundamental frequency = 1st harmonic.The following tones have a higher frequency:2nd harmonic = 1st overtone.3rd harmonic = 2nd overtone.4th harmonic = 3rd overtone.5th harmonic = 4th overtone.6th harmonic = 5th overtone.Look at the link: "Calculations of Harmonics from Fundamental Frequency".


How can two square waves be combined in an electronic circuit?

If they are the same voltage a logic gate could combine them in various ways. A ring modulator fed from two square waves would make interesting sounds. An op-amp would combine the waves. A single fet would combine them. One signal flowing from source to drain modulated by the second frequency applied to the gate.

What are the different parts of a modem?

features? Well, the "features" of a true standard 56k modem are that it accepts and sends information in bits and packages through a phone line. DSL and Cable modems are different. They actually convert data back and forth for a higher stream range. I suggest you goto howstuffworks.com. They have an extensive area for modems and networking materials.
