摘要：
An input circuit is described for accepting different types of input signals.
An instruction means (14,86) selects a first mode when an input reference signal is given, and a second mode when it is not. In the first mode, the input voltage is compared with the input reference signal, whereas in the second mode the threshold is a predetermined threshold.
