You must sample at 2 x the rate of the analog signal (2 x the analog signal frequency).

Differentiate between natural sampling and flat-top sampling?
The natural sampling is one which can be represented with respect to amplitude of the analog signal.The flat top sampling is the one which can be represented in only a particular amplitude which cannot be changed with respect to the analog signalthis is true but let me add another difference that Is The Noise ...In Natural sampling : the sample take the top signals shape ( respect to amplitude of the analog signal ) which mean if there is noise above signal , when it will be demodulate with LBF (low pass filter ) it will cut from the original signal ,,,, We cant do that ...but In Flat-Top sampling : the sample shape will be lated so if there is noise we can remove it easily and the signal we be like it transmitted without any noise ...
What is an analog clock?
An analog clock is a clock with numbers in a circle and a minute and hour hand to tell the time.
What are examples of quantities that are analog?
All quantities in nature are analog. This is a rule of thumb that can be used to find out if a quantity is analog or not.examples of analog quantities aresound(from natural sources)vision etc.Analogue quantities are ones that change continuously.It is easy to misread this definition, what it doesn't mean is that analogue quantities are ones that change continually, or all the time.
What are clocks with hands called?
Analog clocks.
What is the analog method?
The analog method is a difficult way of making a weather forecast. It requires the forecaster to remember a previous event that should mimic an upcoming event.
Is Nyquist theorem true for optical fiber?
I cannot see where the Nyquist theorem relates to cables, fiber or not.The theorem I know, the Nyquist-Shannon sampling theorem, talks about the limitations in sampling a continuous (analog) signal at discrete intervals to turn it into digital form.An optical fiber or other cable merely transport bits, there is no analog/digital conversion and no sampling taking place.
Why you are using sampling theorem in communication systems?
sampling is a one type of process use for converting into analog signal to digital signal.
What is the advantage of sampling analog signal?
1-What are the advantages of sampling analog signals?2-what are the following terms mean : instantaneous Sampling , Natural Sampling , and Flat-top Sampling ?3- what are the advantages of digital communication over analog communication ?4-Explain the reason for making the sampling frequency greater than or equal to (2B)Hz , where B is the bandwidth of the analog signal
What is meant by sampling in analog to digital conversion?
while conversion of analog signal to digital signal, we need to convert continuous analog signal to discrete signal. this can be done by dividing the analog signal into specific time slots. this process is known as sampling. there is a condition for sampling that can be given as follows. fs<=2fm
What is sampling thearm cocerning the rate of sampling required for analog signal?
It states that for satisfactory representation of the sampled signal the sampling frequency must be atleast equal to twice the highest input freq, which is called nyquist sampling. If its less than twice, undersamplin occurs resulting in distortion.
What is the number of times an analog wave is measured each second during an analog-to-digital conversion?
the Sampling Rate.
What describes the number of times an analog wave is measured each second during an analog-to-digital conversion?
The sampling rate
Which of the following describes the number of times an analog wave is measured each second during an analog-to-digital conversion?
Sampling Rate.
If an analog signal with bandwidth of 1.7khz is to be digitized what time intervals should the analogy signals be sampled?
The theoretical minimum sampling rate required in order to avoid frequency aliasing is 3.4 KHz.
What is the sampling rate in Hz?
Sampling rate is a defining characterstic of any digital signal. In other words, it refers to how frequently the analog signal is measured during the sampling process. Compact disks are recorded at a sampling rate of 44.1 kHz.
What is analog signal?
An analog signal is a continuous signal that contains time-varying quantities. Unlike a digital signal, which has a discrete value at each sampling point, an analog signal has constant fluctuations. netonplus.com
What is sampling frequency?
Sampling is the process of splitting analog signals intodigital signals.In Frequency Sampling the frequencies in a particular values split-ted according to the time, it will be split-ted intodigital values like binary values.
