Why is it necessary to modulate the picture and sound signals before transmission?
To avoiding the noise signal effect.Because the modulation is a technic which providing a high characteristic to transmitting the signal on long or short distance.Because the modulated signal received as high bandwidth,high performance of received signal and the modulation Technic is provide a less hight of antenna in wireless transmission which is expressed in the term :(hight of antenna=λ/4).
What is an carrier amplifier?
It is a direct-current amplifier in which the dc input signal is filtered by a low-pass filter, then used to modulate a carrier so it can be amplified conventionally as an alternating-current signal; the amplified dc output is obtained by rectifying and filtering the rectified carrier signal.
Which law gives the direction of induced current?
LENZ LAW gives the direction of induced current.
What is the wire that gives off light in a light bulb?
In an incandescent light bulb the wire that gives off the light is called the Filament.
Why use of Multivibrator?
it gives a nice pleasurable experience
What are the functions of the MODEM?
Modulate Demodulate
Is the word modem an acronym for modulate-demodulate?
modulator-demodulator
What 2 words are used to make up the word modem?
modulate and demodulate
Explain the meining of modem?
Modem stands for MOdulate DEModulate it takes digital information from your computer and turns it into sound (the MOdulate portion) and turns sound into data (the DEMod part)
Is modem an adverb?
No, it is not an adverb. The word modem (from modulate-demodulate) is a noun, a device that changes electrical impulses into sound, and vice versa.
What is a device that translates computer signals to analog signals suitable for sending across phone lines?
A modem. Short for MOdulate-DEModulate.
What is modem and how does it relate to Dial-Up connection?
"MODEM" stands for "modulate/demodulate" The modem changes digital signals into analog tones that can be sent across a telephone wire.
Whatis the function of modem?
MOdulate/DEModulate. It converts digital computer signals into analog ones for transmission over analog telephone lines, and then converts the signal back into digital on the other end.
Is a modem an input only?
Modem is short for MODulate/DEModulate. It modulates a signal to send across a serial wire, and demodulates the signal that comes back.In other words, a modem is both an input AND an output device.
Why BPSK system is implemented in spartan 3e FPGA kit?
BPSK is a modulation technique. It is used to modulate and demodulate the required signal. It can be virtually implemented in MATLAB. But to understand its physical behaviour, it needs to be implemented on FPGA board.
If you have pics taken on a cannon camera on a SD card and want to use your samsung camera to load through onto your PC why can you not get a preview of the pics?
The photos are stored in a propriatary format to the camera. Only the camera can modulate and demodulate the file to and from a computer.
What is a modems purpose?
1. To MODULATE (convert) the digital signals from a computer into analogue signal to enable it to be carried through the telephone line. 2. To DEMODULATE (convert back) analogue signals from a telephone line into digital signal to be used in computer.
