Use this selector tool to quickly identify the best power supply for your aerospace and defense ATE requirements. 3D Interconnect Designer provides a flexible modeling and optimization environment for any advanced interconnect structure, including chiplets, stacked die, packages, and PCBs. It involves measuring the rate at which errors occur in a transmitted bitstream compared to the expected bitstream at the receiver end. The BER measurement helps in assessing the quality. This topic describes how to compute error statistics for various communications systems. The biterr function, discussed in the Compute SERs and BERs Using Simulated Data section, can help you gather empirical error statistics, but validating your results by comparing them to the theoretical error. In digital transmission, the number of bit errors is the number of received bits of a data stream over a communication channel that have been altered due to noise, interference, distortion or bit synchronization errors.
