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 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.
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.
How Frequency Modulation Have Higher Bandwidth then AM?
Bandwidth is defined as difference between two frequencies.In AM only amplitude is modulated or changed to transmit the data at the given fixed frequency. In FM the frequency of the signal is changed to transmit the data. Since we will need a range of frequency to transmit the data using FM (say frequencies from f1 to f2), the bandwidth of FM signal will be higher than AM signal which can transmit at a fixed frequency.But.....The above answer does not address the issue of "strength of modulation", that is, modulation index.A.M. will always have a bandwidth of twice its highest modulating frequency regardless of the strength of modulation.For voice comms with about a 3 kHz maximum frequency, A.M. will demand (3+3) = 6 kHz of bandwidth.Because F.M. modulates the frequency swing of the transmitter, low modulation indexes with F.M. can give a bandwidth LESS than the maximum modulating frequency. Narrow-Band F.M. (NBFM) can have a bandwidth of *less than* 3 kHz, indeed it can have a bandwidth of only a few hundred hertz, in theory.In practice, very narrow NBFM suffers from worsening signal-to-noise ratios, and one of F.M.'s chief advantages over A.M. is the superior signal-to-noise of F.M. when it is allowed sufficient bandwidth.
An analog signal with a bandwidth of 1.5khz is to be digitalised what time intervals should the analog signal be sampled?
as a general rule of thumb, about 5 times the highest frequency for quality reproduction, although one can sometimes get away with a minimum of 2 times. 7.5KHz

What is the ideal sampling frequency?
Not less than double the highest frequency component of the signal you're sampling.
What types of radiation has the highest frequency?
In the electromagnetic spectrum Gamma radiation has the highest frequency.
What is the highest frequency in electromagnetic spectrum?
The highest frequencies of waves are gamma rays.
Which type of em spectrum has the highest wavelength?
The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
Which have the highest frequency in the electromagnetic spectrum?
Gamma rays
What color of light in the visible spectrum has the highest frequency?
The highest frequency/shortest wavelength of visible light isthe last color you can see on the blue end of the spectrum.
What part of the electromagnetic spectrum has the greatest frequency?
If by greatest frequency you mean highest frequency, we know that the upper end of the electromagnetic spectrum has the greatest frequency. This is the home to the gamma rays. They have the highest frequency, shortest wavelength, and the greatest energy.
Which wave has the highest frequency in the electromagnetic spectrum?
Gamma Rays
Which band of the electromagnetic spectrum has the highest frequency?
gamma radiations..
What part of the spectrum has the highest frequency?
The part with the shortest wavelength has.
What is the highest frequency on the em spectrum?
I don't think there is a limit, as to how high the frequency can get. The EM waves of the highest energy (and frequency) are called "gamma rays".
