Analog reconstruction of asynchronously sampled signals from a digital signal processor

摘要: A sample reconstruction device and method extracts digital values from a DSP that are samples of signal interest reconstructs the into an equivalent analog signal. context detector monitors DSP's operation determines when value being processed by is interest. The may be implemented using logic analyzer, emulator system, or itself. probe input selected for buffering system having FIFO buffer memory control loop employed to ensure interval substantially constant, even if there great deal variation between intervals. reconstructed accurately represents found within DSP. This then sent specialized test equipment suited analysis signals.
