What was before digital?
Analog transmission came before digital ones
How fast is transmission from analog to Digital?
Analogue to digital is a conversion process not a transmission process.
Difference between digital transmission and digital modulation?
The Difference of two is only first digital has a transmission and second digital has modulation.....thats all....i think that's too clear ha...
Which type of digital transmission should you use?
synchronous serial transmission
Why digital transmission is preferred than analog transmission?
Faster responce.
What are the characteristics of digital transmission over analog?
Error can be easily detected in digital.
What has the author Irwin Lebow written?
Irwin Lebow has written: 'The digital connection' -- subject(s): Digital electronics, Popular works 'Understanding digital transmission and recording' -- subject(s): Digital modulation, Sound, Data transmission systems, Recording and reproducing, Digital techniques
How are digital signals in radio broadcast converted to analog signals inside digital transmission equipment before sending the signals to the antenna for transmission?
The digital signals is not converted BACK to analog! it is transmitted in digital form and the receiver is converting it back to analog to drive the speakers. The signal from the microphone is converted from analog to digital with an A/D converter chip, digital signals consist of pulses of different lengths that is switching the transmitter on and off in about the same way as the old Morse code transmissions but at a much higher rate (millions of times higher)
What digital transmission method was created in 1984?
ISDN
What is digital data transmission?
Digital data transmission use voltage differences to directly represent the 1s and 0s that make up the data and are not modulated over a carrier.
What is a set of standards for digital transmission of data over standard copper telephone lines?
The set of standards for digital transmission of data over standard copper telephone lines is ISDN
What is the difference between analog and digital data transmission?
This is essentially the same question as the difference between analog and digital. With analog electronics a voltage is used to represent (or to be an analogy for) some physical attribute in the real world. So for an analog transmission, at its simplest, a sound signal (say) is converted to a voltage, the voltage sent down a cable, then at the other end the voltage converted back into sound with a loudspeaker. With a digital system, the physicial attribute is measured and sent as a series of numbers, the numbers being converted to binary. For a digital transmission, the sound signal is converted to a series of numbers, sent as binary, and converted back to a sound signal at the other end. The advantages of digital is that it makes multiplexing much easier - making it easier to put many signals down the same physical cable. It also makes compressing the signal much easier - this is particularly effective for digital television transmission; 30-40 digital channels can be sent over the same bandwidth as 4 or 5 uncompressed analog channels. Also, digital is much more resiliant against noise - the digital receiver has to make a decision about each bit - is it there or not; noise can be pretty extreme before this becomes impossible, with analog, once noise is added its very difficult to remove it. The historical disadvantage of digital is that digital encoding and decoding equipment was expensive compared with the analog. Over the last 10 years or so, digital electronics has become much cheaper and more powerful.
