Consequently, real reconstruction filters typically either allow some energy above the Nyquist rate, attenuate some in-band frequencies, or both.
12.
According to the OED, Black's statement regarding 2 " B " may be the origin of the term " Nyquist rate ".
13.
More complex transmissions like PAL / NTSC ( TV ), A / D at a rate faster than the nyquist rate that is at least the IF frequency.
14.
:: : The standard sampling rate for telephony is 8000Hz, which due to the Nyquist Shannon theorem means the highest frequency transmitted is 4000Hz ( see Nyquist rate ).
15.
Long before Harry Nyquist had his name associated with sampling, the term " Nyquist rate " was used differently, with a meaning closer to what Nyquist actually studied.
16.
Actually I am uncomfortable with my lack of relating the 16-bit sample size to the Nyquist rate and perception . talk ) 19 : 41, 12 January 2010 ( UTC)
17.
Thus, " Nyquist rate " is a property of a continuous-time signal, whereas " Nyquist frequency " is a property of a discrete-time system.
18.
To achieve high signal-to-noise ratio, delta modulation must use oversampling techniques, that is, the analog signal is sampled at a rate several times higher than the Nyquist rate.
19.
:If the sampling theorem is interpreted as requiring twice the highest frequency, then the required sampling rate would be assumed to be greater than the " Nyquist rate " 216 MHz.
20.
The Nyquist frequency should not be confused with the " Nyquist rate ", which is the minimum sampling rate that satisfies the Nyquist sampling criterion for a given signal or family of signals.
