    Proper hardware validation and stress tests before mass production can save millions of dollars on recalls and redesigns. In this application note, the Moku:Go Logic Analyzer/Pattern Generator will be utilized to validate a digital 4-bit adder by toggling inputs and recording the corresponding outputs. Furthermore, the clock rate will be varied to stress test the…

    Signal digitization is an essential step to enable digital signal processing (DSP). It converts an analog signal to discrete-time binary numbers and allows the signal to be processed with digital logic devices, such as CPUs, application-specific integrated circuits (ASIC), and field-programmable gate arrays (FPGA). To ensure the conversion process retains the maximum signal fidelity, the…
