Webb15 nov. 2024 · Precision and accuracy in oscilloscopes. November 15, 2024 By David Herres 3 Comments. The precision and accuracy of voltage measurements made with a digital scope are affected by the speed at which samples are taken, i.e. the sampling rate, and sampling depth or bit depth. Bit depth is just the number of bits of information in … During the late 1920s, Harry Nyquist and Ralph Hartley developed a handful of fundamental ideas related to the transmission of information, particularly in the context of the telegraph as a communications system. At the time, these concepts were powerful breakthroughs individually, but they were not part of a comprehensive theory. In the 1940s, Claude Shannon developed the concept of channel capacity, based in part on the ideas of Nyquist and Hartley, and then formula… pomona to beverly hillsWebb5 juni 2008 · Let us derive the theoretical 16QAM bit error rate (BER) with Gray coded constellation mappingin additive white Gaussian noise conditions.
