Abstract
The invention relates to a trigger circuit which compares amplitudes of the signal waveform of a periodic signal to reference values dependent upon the previous signal waveform of this signal. A trigger signal is emitted when the particular reference value is reached. The trigger circuit includes a memory for the particular reference value. The reference value is determined from a portion of the period of the signal to determine a precise triggering point.
