摘要：
A number of separate comparators compare respective analog inputs to a single reference waveform and turn off respective gates when the analog voltages achieve predetermined relationships to reference wave form. The gates pass pulses from a common source from the beginning of the reference wave form until the respective gates are shut off. In one version the analog signals represent photographic data such as diaphragm aperture and shutter speed in a camera, and are digitized for display within the camera.
