Maximum representable frequency
"The sample rate of a system defines the maximum representable frequency, which is half the sample rate." This is not correct, and is a common misstatement—the sample rate must be greater than twice the maximum representable frequency, not greater or equal to it. So, you can only represent frequencies less than half the sample rate. For instance, if your samples of a sine wave at half the sample rate coincide with zero crossings, you get nothing.Earlevel (discuss • contribs) 23:16, 5 February 2012 (UTC)
