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 else can I help you with?
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.
Is anti aliasing filter analog or digital?
It must be an analog filter. The high frequencies must be attenuated before any digital sampling takes place, to ensure that these high frequencies are not sampled as false signals. See the related link.
Why digital signals have infinite bandwidth?
Digital signals can theoretically have infinite bandwidth because they are composed of discrete values that can switch between states at very high frequencies. Each transition between these states, particularly in pulse-width modulation or other encoding schemes, can require a significant amount of frequency to accurately represent the sharp changes. Additionally, the use of techniques like oversampling and high-frequency clock signals can introduce additional harmonics, further expanding the signal's bandwidth. However, practical limitations such as noise and physical medium constraints typically restrict the effective bandwidth in real-world applications.
What is difference between digital signals and non continuous signals?
hi, actually non-continuous signals is one of a characteristics which define a Digital Signal.#non-continuous means having a finite or countably infinite number of values, which is exactly a defining property of a digital signal. therefor its not right (wrong) to ask the difference between the two.hope it help. :)
Advantage of digital signal?
Higher immunity to noise, storage of digital signal is cheap and easy, its representation is only using two levels as opposed to infinite levels for analog
What are the values that digital signals have?
digital signals have two values. 0 and 1.
How are digital signals?
Digital signals are measured in bits per second (bps).
What is the range of frequencies?
there are an infinite range of frequencies limited only by the mechanical limitations of the medium creating and transferring it.
What converts your voices sound waves to digital signals?
A microphone converts voice sound waves into electrical signals, which are then digitized by an analog-to-digital converter (ADC) to produce digital signals. These digital signals can then be processed and transmitted digitally.
Which of digital signals and analog signals are more vulnerable to error?
Analogue signals are more vulnerable to error than digital signals. See the related question "Why digital signals are more noise free than analogue signals?" for more details.
Why do digital signal require timing signals?
To measure time between digital signals.
How are digital signals measured?
Digital signals are measured in bits per second (bps).
