초록 ▼

A system and method are provided for determining the occurrence of transitions in a binary encoded analog input signal. The system includes a threshold circuit, responsive to the input signal, for generating first and second grating signals in dependence upon whether the input signal exceeds or is less than a first threshold level, respectively. A first circuit means, responsive to the input signal, differentiates the input signal to form a first derivative signal. A threshold circuit, responsive to the first derivative signal, generates third and fourth gating signals in dependence upon whether the first derivative signal exceeds a second threshold level or is less than a third threshold level, respectively. A second circuit means, responsive to the first derivative signal, differentiates the first derivative signal to form a second derivative signal. The second derivative signal has zero crossings which are detected by a zero crossing means, responsive to the second derivative signal and to the first, second, third and fourth gating signals.
