What is Skew?

Written by Erdem on 12:49 PM with No comments

Skew is defined as the difference in propagation delay between two or more signal paths. Skew is of greatest concern between two conductors of a differential pair. If both path lengths aren’t matched precisely, skew in a differential pair can lead to increased Insertion Loss, Impedance Mismatch, Crosstalk and EMI. Low skew between multiple paths can be important in a parallel...

What is Nyquist Frequency?

http://www.dnr.state.oh.us/tabid/8170/Default.aspx Nyquist Frequency The Nyquist frequency is the bandwidth of a sampled signal, and is equal to half the sampling frequency of that signal. If the sampled signal should represent a continuous spectral range starting at 0 Hz, the Nyquist frequency is the highest frequency that the sampled signal can unambiguously represent.ExampleIf a signal is...
