摘要： The invention concerns a method, device and computer program product for providing increased reliability in the processing of digital signals. The device includes means (20) for performing analog measurement of a received signal (S) intended to occupy two logical states at various instances in time, means (24) for determining if there is a change in the analog signal level, means (24) for determining if the change fulfills at least one logical state change condition, where a first logical state change condition is based on the speed of change of the analog signal level, and means (24) for determining that there is a change from one logical state to the other if at least one logical state change condition is fulfilled. The invention provides secure detection of unreliable digital signals that may be generated in harsh environments that are polluted or moist.
