What is the sampling rate at Nyquist frequency?

Solution The bandwidth of a low-pass signal is between 0 and f, where f is the maximum frequency in the signal. Therefore, we can sample this signal at 2 times the highest frequency (200 kHz). The sampling rate is therefore 400,000 samples per second. What happens at Nyquist frequency?

What is the lower bound of Nyquist rate?

The lower bound 2 B is often called the Nyquist rate. If you sample a signal s ( t) at f s samples per second, then f N = f s / 2 is frequently called the Nyquist frequency (also folding frequency). All frequencies in s ( t) higher than f N will be aliased back to a frequency between 0 and f N.

What is the Nyquist criterion?

Simply stated, the Nyquist criterion requires that the sampling frequency be at least twice the highest frequency contained in the signal, or information about the signal will be lost. If the sampling frequency is less than twice the maximum analog signal frequency, a phenomenon known as aliasing will occur.

What is the Nyquist frequency in units of radians?

Nyquist=1/(2dt) as the Nyquist frequency ; in units of radians we have? Nyquist=?/dt. Another way of stating the Sampling theorem is that the highest frequency in the data should be less than the Nyquist frequency.
