Circuiti e procedimenti per effettuare il debouncing di segnali prodotti da un trasduttore di posizione angolare

A circuit (6) configured to debounce signals (IN1, IN2) produced by a quadrature encoder is disclosed. A first input node is configured to receive a first input signal (IN1) and a second input node is configured to receive a second input signal (IN2). The first input signal and the second input signal are in phase quadrature. An edge detector circuit (60) is configured to sense the first input signal and produce a pulsed signal (E) indicative of edges detected in the first input signal. A pulse skip and reset circuit (62) is configured to sense the pulsed signal and the second input signal, and produce a reset signal (CLR) indicative of pulses detected in the pulsed signal while the second input signal is de-asserted. A sampling circuit (64) is configured to sense the second input signal and the reset signal, and produce an output signal (IN2 ') by de-asserting the output signal in response to assertion of the second input signal and asserting the output signal in response to a pulse being detected in the reset signal.
