Tell Me About Nyquist Rule?

1.	Tell Me About Nyquist Rule?
Answer» Nyquist Rule is one of the MATHEMATICAL expressions. While sampling the frequency, the sampling frequency is multiplied twice. The signal should not contain a Fourier spectrum with sine or COSINE above the frequency. The signal can be reconstructed by sampling at twice the frequency. The signal can not be reconstructed if the signal is not sampled at twice the frequency. Nyquist is required only for digital signal processing but not for analog SINGNAL processing.
