Accepts pulse input, either random or evenly spaced, and produces output ofter fixed number of inputs. Useful in measuring and recording low. frequency data. Pulse widths may be 1 millisec to several hundred millisec. Output may have anywhere from 2 to 1,000 steps.By making R1 smaller and eliminating R2, output becomes sawtooth with 1% linearity, variable from 10 millisec to 15 minutes depending on values of C1 and R1.-Low.Frequency Stairstep Generator and Timing Circuit, Electronic Circuit Design Handbook, Mactier Pub. Corp., N.Y., 1965, p 144.
