What communication was there in the past?
Carrier pigeons, smoke signals, animal sounds, mail, telegraphs. Hope this helps :)
What was the communication in past?
Depends how far you go back in the past, as to how the communicated, but theres smoke signals, telegraphs, carrier pigeons, animals sounds, and early telephones.
Can someone please explain the difference between OCN and SPID Telecom VoIP?
The difference between OCN and SPID Telecom VoIP is that the OCN is assigned by The National Exchange Carrier Association and is used as an identifier for inter-carrier transactions while the SPID is the Service Provider Identification Number.
What is the difference between coherent demodulation and non coherent demodulation?
In case of coherent demodulation carrier used for demodulation purpose is in phase and frequency synchronism with carrier used for modulation purpose. For non-coherent demodulation it is not in synchronism.
Difference between dsb fc dsb sc?
DSB-FC means 'dual sideband full carrier' where DSB-SC means 'dual sideband suppressed carrier'.With DSB-SC the carrier wave is suppressed so that almost all the power transmitted is in the sidebands. See the wikipedia page for more info
Differences between baseband and broadband?
Baseband is a type of transmission that uses current to send a signal over the wire as digital wave. Broadband uses analog signal to transmit thru different frequencies, which increases the amount of data carried at one time.
Why carrier signal is always in analog signal?
It isn't always. Baseband analog signals have no carrier.
Is demodulated carrier wave grounded in environment. if yes how. if no what happens to it?
During demodulation of AM the carrier beats with the sidebands reproducing the baseband signal. In other systems it is more complex, but in all the carrier is removed by the demodulator and baseband filter that follows the demodulator.
What is baseband connection?
Electrical signals are found in different parts of the frequency spectrum. A baseband signal is an "original" signal that directly conveys the frequency range of the original: a hi-fi audio signal is commonly 20 Hz to 20 kHz, analog video (European) is 50 Hz to 5 MHz. A baseband signal *does not* use a modulated carrier, no matter how high or low its frequency. Any signal that *does* use modulation is *not* a baseband signal. Radio (and other) transmission systems use the baseband signal to modulate a carrier before sending. On reception, the modulation is extracted to become a copy of the original baseband signal.
What is the difference between baseband coaxial cable and broadband coaxial cable?
Iam pretty sure that baseband coax was 50 ohm and was used for networking computer, were broadband coax is 75 ohm and used in the cable tv industry. A baseband signal is the original signal before it is modulated onto a carrier, mulitplexed or mixed. A broadband signal contains many channels which have been modulated or multiplexed onto a common carrier. The significant difference is the bandwidth of each. The impedance of the cable which carries either of them is totally irrelevant to the definition.
What is bandwidth required for AM signal?
With full double sideband AM the bandwidth of the modulated signal is twice that of the baseband information signal. With suppressed carrier single sideband AM the bandwidth of the modulated signal is identical to that of the baseband information signal. With vestigial sideband AM the bandwidth of the modulated signal is somewhere between the above two cases, depending on how much of the vestigial sideband is included.
What are the difference between carrier signal modulating signal modulated signal baseband and passband?
carrier signal- use for the purpose of conveying information. modulating signal- causes variations in some characteristics of carrier signal. modulated signal - carrier signal after altration in its characteristics is called modulated signal. example- if you want to see an object (suppose it is an modulating signal),you need light(light is carrier signal) and when light will reflect on object you will be able to see if (that is modulated signal)
What is baseband filter?
A baseband filter is a device that only passes frequencies inside the interval (0,B), where B is the maximum frequency of the signal.Example: The human voice occupies a spectrum from 0 Hz to 3400 Hz, aproximately. A baseband filter would only let those frequencies pass.The difference between a band-pass and a baseband filter is that the latter is a band-pass filter with its lower cut frequency being 0.
What type of technology is used in DSL?
At the simplest level of explanation: frequency division multiplexing (FDM) with a 3 KHz baseband for telephone audio, a wider modulated carrier band for internet data, and sometimes one or more 6 MHz modulated carrier bands for TV station signals. The exact technical and electronic design details are somewhat different in different versions of DSL.
What is different between carrier and future?
Carrier- which carries something and Future- indicating an action which will take place at a later time.
What animals can represent communication?

What colleges offer Electrical Engineering Courses in Maryland?
In the previous sections of this chapter, we investigated the effect of slowly varying the amplitude of a sinusoidal carrier wave in accordance with the baseband (information carrying) signal. There is another way of modulating a sinusoidal carrier wave, an
