A glitch filter includes a storage element for storing a current state, which is the output of the filter. An output of the storage element is-connected to one input of a state comparator. Another input of the state comparator is connected to an input signal. A programmable clock delay is connected between the state comparator and the storage element. The programmable clock delay may provide a programmed duration independent of the technology used for implementation. The glitch filter is arranged such that the input signal is stored as the new current state in the storage element only if the input signal changes and then remains unchanged for the programmed duration.
