Bandwidth of digital signal is infinite?
A digital signal is actually a complex signal. Consider the horizontal part of a digital signal as a component with 0 frequency and the vertical part of the signal as the component of infinite frequency. Also, consider the change from the horizontal to vertical as all the frequencies. Then we can claim that a digital signal is complex signal with frequencies from 0 to infinite.A digital signal is a composite analog signal with an infinite bandwidth.
What is an analog-to-digital converter?
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
What is the baud rate of a digital signal?
the digital signals frequency is infinite ,i.e ranges from 0.....infinity
Is digital signal frequency 0 Hz?
No, a digital signal does not have a specific frequency like an analog signal. Digital signals are represented by discrete values at specific time intervals and are typically transmitted using square waves with a fundamental frequency determined by the data rate.
How do you send a digital radio signal to a FM radio?
Frequency Modulation must have a carrier whereby the frequency can be modulated by the signal
What is a frequency transducer and how it works?
This is an electronic device which converts electrical signal into a digital signal.
Why digital signals has infinite frequencies?
Some might equate a digital signal frequency as the bit rate per second. However, this measures the clock rate that encodes and decodes the digital pulse train. If you looked at frequency as being the repetition rate of a unique waveform and assumed that the digital pulse train never repeated the frequency would be the cycles of the repeating single over time. By this measure a signal that didn't repeat would go on continually as it tried to become infinite. There are a lot of assumptions made in this definition and the results are not very useful unless it is a thought experiment or a test of some sort.
What is convert analog to digital convert?
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
Why it is generly true that a digital signal required high bandwidth than analog signal?
A: Analogue signal Direct voltage that varies in the low spectrum of frequency on digital signal the information is deciphered in micro seconds therefore the frequency must be hi the higher the better.
The difference between Digital signal and analog signal?
I'm not sure if you are speaking of a specific instance.... However, a digital signal is a binary representation of the analog signal. The analog signal is constantly measured and the amplitude (voltage at the time of sample) of the analog signal is converted to a binary number at specific intervals (the frequency of the sample rate). The higher the frequency of the sample rate, the more accurate the representation of the analog signal.
Why you need modems on digital circuits?
In digital circuits modem is used to multiplex and demultiplex the digital data.multiplexing means the digital signals amplitude or frequency or phase is varied with a carrier signal.at the receiver end the carrier signal is separated out and original digital signal is received
Why do you use modem?
modem means modulator demodulator. it converts digital signal to analog signal. it is use to transmit computer signal (digital signal) over the telephone line to communicate to other computers. modem converts the computer digital signal into frequency (analog signal) so that it can transmit over the telephone line and at the receiving end the modem converts the analog signal back to digital for the receiving computer to understand it.
