Digital peak detection among multiple signals, or inputs. In one embodiment, a detection method that includes receiving multiple digitized input signals. For each digitized input signal, the method also includes noting a first data value associated with the digitized input signal at a first time. The method includes comparing the first data values to determine a largest first data value from among the first data values. For each digitized input signal, the method includes noting a second data value associated with the digitized input signal at a second time. The method includes comparing the second data values to determine a largest second data value from among the second data values. The method includes comparing the largest second data value with a threshold data value. The method includes detecting a peak when the largest second data value is greater than the threshold data value, and less than the largest first data value. In other embodiments, devices that includes a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC) that is configured to perform at least the steps of this detection method. That is, the FPGA or the ASIC can be provided with logic, or programming, that can be utilized in performing the steps of this detection method.
