What would be the minimum sampling interval needed for reconstructing a signal where the highest frequency is 1 kHz?

The Nyquist frequency for a signal with a maximum bandwidth of 1 KHz is 500 Hz, however that will lead to aliasing unless perfect filters are available.
The Nyquist rate for a signal with a maximum bandwidth of 1 KHz is 2 KHz, so the answer to the question is 2 KHz, or 500 microseconds.

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 relationship between sampling rates and frequency of the modulating signal when using pulse modulation?
The sampling rate must be at least double the highest frequency component of the modulating signal in order to avoid frequency aliasing.
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 does digital recording do to an analog sound wave?
It quantizes it into discrete points represented by zeros and ones (digital information). The number of samples must be at least two times the highest frequency component of the analog wave. The number of bits in each sample determines how close the digital information is to the actual value of the analog signal.
What are numerical relays?
As we know numerical relays use DIGITAL SIGNAL PROCESSOR as its computational hardware and based on microprocessor. WORKING: Analog input is feed into the anti aliasing filter which is a low pass filter.Output of this filter is feed into the sample and hold circuit , frequency of sampling should be twice of our highest frequency of interest(according to the nyquist criterion).if sampling frequency kept low than aliasing input may occur. after the sampling, signal are feed into the multiplexer,where all the signal get multiplexed and we have a single signal.this signal is feed into the analog to digital converter.this digital signal is feed into the microprocessor and microprocessor generates control signal according to its input. for example if you are using N.R. for over-current protection than you should set a value of current in your program.if the value of current passes through the circuit is greater than the set value..than N.R. enables the circuit breaker and hence our system is protected..
What is the ideal sampling frequency?
Not less than double the highest frequency component of the signal you're sampling.

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 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 the relationship between sampling rates and frequency of the modulating signal when using pulse modulation?
The sampling rate must be at least double the highest frequency component of the modulating signal in order to avoid frequency aliasing.
What is the highest sampling rate if the input frequency is 3 kHz?
According to Niquest Theorem, it has to be more than twice the input frequency.
What is high modality?
it is a strong word that is used in expositions and arguments if data is in the form of frequency distribution then the modal range is the interval containing the highest frequency of observations
Why you need to measure extremely small interval of times?
We need small values of delta t as the smaller is the time interval better resolution of signal is possible. Also, the highest frequency in frequency domain is inversely proportional to delta t. So higher delta t in time domain results in higher the maximum frequency in frequency domain.

Which waves have the highest frequency?
Gamma rays emit the highest frequency.
Why do audio CDs have a frequency of 44.1 KHz if people can only hear up to 20 KHz?
The 44.1KHz frequency is the frquency of the 'sampling rate' With digital audio the original analog signal has to be 'sampled' ie measured. These samples measure the amplitude (strength) of the signal at that particular point in time. Since the analogue signal is constantly changing the sampling must be done continuously. The sampling rate must ALWAYS be higher than the highest frequency of the source signal, (otherwise it cant be measured). There was a bloke called Nyquist who postulated that the sample rate must be at minimum twice the highest frequency of the sample. This has been accepted as common practice now. This is where we get 44K (ie 44,000 measurements or samples per second), which is about double the 20K audio source.
What is the mode of grouped and ungrouped data?
If you have calculated a histogram of your data, the mode is the interval with the highest relative frequency. If you have not created a histogram, and your dataset contains finite numbers (fixed decimal numbers), with some numbers repeating, then those numbers that repeat the most would be the mode. Otherwise, if you do not group your data, where you select an interval to calculate relative frequency, then a mode is not identifiable.
What types of radiation has the highest frequency?
In the electromagnetic spectrum Gamma radiation has the highest frequency.
