Digital signal

Digital signal | Discrete time and value, i.e. step-shaped measurement, regulation or control signal with digital information. Information carriers can be the level (pulse height = y-value), various edge distances (pulse duration, perionde duration = distances between two x-values) or the frequency (periodic edge sequence). In measurement technology, digital signals are often square-wave signals or approximate square-wave signals. Within certain value limits (e.g. voltage values: high level: 5 ... 50 VDC), they ideally only assume two values: High or Low, 1 or 0.
