State sampling theorem?
sampling theorem is defined as , the sampling frequency should be greater than or equal to 2*maximum frequency, and the frequency should be bounded.. i,e fs=2*fmax where fs= sampling frequency
What is the nyquist sampling rate and nyquist frequency for frequency f equals 0?
The Nyquist sampling rate is defined as twice the highest frequency present in a signal to avoid aliasing during sampling. For a frequency ( f = 0 ), the Nyquist sampling rate would also be ( 0 ) since there are no oscillations to capture. Consequently, the Nyquist frequency, which is half of the sampling rate, is also ( 0 ). This means that no information can be effectively captured or reconstructed from a signal that is constant (i.e., with a frequency of zero).
If the frequency spectrum of a signal has a bandwidth of 500 Hz with the highest frequency at 600 Hz what should be the sampling rate?
The Nyquist Therorem states that the lowest sampling rate has to be equil to or greather than 2 times the highest frequency. Therefore the sampling rate should be 400Hz or more.
What is the minimum sampling rate if the input frequency is 3 kHz?
According to the Nyquist theorem, the minimum sampling rate must be at least twice the maximum frequency of the input signal to avoid aliasing. Therefore, if the input frequency is 3 kHz, the minimum sampling rate should be 6 kHz.
What is the effect of sampling frequency on demodulation output?
The sampling frequency significantly impacts the accuracy and fidelity of the demodulation output. If the sampling frequency is too low (below the Nyquist rate), it can lead to aliasing, resulting in distortion and loss of information. Conversely, a higher sampling frequency allows for better representation of the modulated signal, leading to more accurate demodulation and improved signal quality. However, excessively high sampling rates may introduce unnecessary complexity and increase processing requirements.

What is the ideal sampling frequency?
Not less than double the highest frequency component of the signal you're sampling.
What are the differences between natural sampling and pulse amplitude modulation?
In pam dc shift is present which will not present in natural sampling.
How does the sampling oscilloscope increase the appearent frequency response of an osciloscope?
A: A sampling scope is not real time scope but rather a hi frequency rate of sampling which benefit the observer
What is the relation between sampling frequency and wave frequency?
There is no factual relation between these, but there is a common rule known as the Nyquist-Shannon theorem, that states that to reproduce a waveform with only reasonably errors, the sampling frequency must be at least twice the wave frequency.
What Steps to take when selecting a suitable sampling frequency?
The Nyquist Theorem says that the sampling frequency should be twice the bandwidth to avoid aliasing. Thus if the bandwidth of the system is bw then the sampling frequency f=2*bw.
If sampling frequency doubles then what happens to quantization?
If the sampling frequency doubles, then the quantization interval remains the same. However, with a higher sampling frequency, more quantization levels are available within each interval, resulting in a higher resolution and potentially improved signal quality.
What is the difference between sampling frequency and frequency?
frequency is simply the rate at which something is happening, ie the frequency of Christmas is once a year, the frequency of having breakfast is once a day etc. If frequency is expressed in Hertz, it's how many times something happens during a second. Sampling is, well, sampling. Usually means testing and measuring something changeable. If you're running a bath and occasionally stick your fingers in to check the temperature, then that's sampling, Sampling frequency simply describes at which rate you're making whatever test or measurement it is you're talking about.
What uis the sampling rate for PCM if the Frequency ranges from 1000 to 4000 Hz?
As we know that the sampling rate is two times of the highest frequency (Nyquist theorm) Sampling rate=2 Nyquist fs=8000hz/8khz
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.
If sampling frequency doubles then quantization noise?
reduces
If the frequency spectrum of a signal has a bandwidth of 500 Hz with the highest frequency at 600 Hz what should be the sampling rate?
The Nyquist Therorem states that the lowest sampling rate has to be equil to or greather than 2 times the highest frequency. Therefore the sampling rate should be 400Hz or more.
