    摘要: A peak detector provides repeatable and accurate measurements of the signal amplitude for variable frequencies of input signals. The peak detector includes a pulse edge generator circuit that generates a pulse edge signal in response to the signal peaks of an input signal and a sampler circuit that is triggered to sample the input signal by the pulse edge signal. The pulse edge generator circuit compares the input signal with a delayed version of the input signal to produce a differential signal and generates the pulse edge signal using the differential signal. An analog or digital sampler is triggered by the pulsed edge signal to measure the information, e.g., peak value, of the input signal. One or more delay circuits may be used to align the edges of the pulsed edge signal with the peaks of the input signal.

    摘要: Metrics are defined and collected for an application. The metrics are organized in hierarchical trees with metrics aggregated at each node in the trees. Each tree represents a different permutation of the metrics. A particular metric may occur in more than one tree. A user interface provides a default drill-down that allows users to jump from one metric to another so that only the most useful information is presented to the user. The default drill-down is defined to provide the user with a best practices method to identify and correct problems or errors in the application. Users may modify the default drill-down path.

    摘要: A method and apparatus for reconstructing media at a receiver from a media stream which includes a plurality of data packets wherein each data packet includes at least one media field. The media stream is monitored by a monitoring device and a packet pattern of the media stream is evaluated. An estimating device estimates a media time of at least one lost packet for reconstructing media by a reconstructing device at the receiver.
