What is the Nyquist rate for a 22050 Hz signal?
For example, audio CDs have a sampling rate of 44100 samples/second. At 0.5 cycle/sample, the corresponding Nyquist frequency is 22050 cycles/second ( Hz ). Conversely, the Nyquist rate for sampling a 22050 Hz signal is 44100 samples/second. [A]
What happens if a signal is less than Nyquist frequency?
[A] When the highest frequency ( bandwidth) of a signal is less than the Nyquist frequency of the sampler, the resulting discrete-time sequence is said to be free of the distortion known as aliasing, and the corresponding sample rate is said to be above the Nyquist rate for that particular signal.
What is Nyquist rate?
Similarly, Nyquist's name was attached to Nyquist rate in 1953 by Harold S. Black : If the essential frequency range is limited to cycles per second, was given by Nyquist as the maximum number of code elements per second that could be unambiguously resolved, assuming the peak interference is less half a quantum step.
What is Nyquist's theorem?
If the signal consists of L discrete levels, Nyquist’s theorem states: In the above equation, bandwidth is the bandwidth of the channel, L is the number of signal levels used to represent data, and BitRate is the bit rate in bits per second. Bandwidth is a fixed quantity, so it cannot be changed.
