ABSTRACT:
A level detecting waveform digitizer for repetitively sampling an analog waveform and converting analog samples into representative digital data is provided with a predictive time base circuit for accurately controlling sample timing with respect to a triggering event in the input waveform and a comparator for indicating when the magnitude of the waveform as indicated by the digital data exceeds a predetermined level. The digitizer also includes a counter for counting samples taken and a second comparator for indicating when the sample count reaches a predetermined limit.
