Flexible converter of analog signal into discrete digital one with the example of double integration voltmeter

A flexible converter of an analog signal into a discrete digital one is designed in VisSim modeling environment with the example of double integration voltmeter. Two oscillators are applied for waveform processing algorithm optimization: the first one specifies a fixed time interval for each measurement run, while the second one is a high-frequency impulse oscillator, which forms measuring impulses. The converter employs the original pulse counter assembled per adder circuit using feedback with memory. The capabilities and advantages of the converter are described.
