How do you calculate Nyquist sampling frequency?

The frequency f_n = 1/2Δt is called the Nyquist frequency. When spectra are presented for digital data, the highest frequency shown is the Nyquist frequency. For IRIS broadband seismic stations, Δt = 0.05 s, so the Nyquist frequency is 10 Hz.

What is Nyquist formula?

The Nyquist formula below provided a relationship between capacity and bandwidth under idealized conditions where noise is not considered. C(bps) = 2B * log₂M (Nyquist) C is the capacity in bits per second, B is the frequency bandwidth in Hertz, and M is the number of levels a single symbol can take on.

What is the Nyquist frequency of a 20 kHz signal?

Knowing that, if we decide that the highest frequency we're interested in is 20 kHz, then according to the Nyquist theorem, we need a sampling rate of at least twice that frequency, or 40 kHz.

How do you calculate Nyquist and Nyquist interval?

The Nyquist rate of g(t) is therefore 400 Hz, and the Nyquist interval is 1/400 seconds. (c) g(t) = sinc(200t) + sinc2(200t) SOLUTION: The bandwidth of g(t) is determined by the highest frequency content of either sinc(200t) or sinc2(200t).
