Generates pulse with 100-ns minimum width in range of 125-250 Hz for application to reset input of Teledyne Philbrick A/D converter in applications requiring un attended operation with continuous conversion. Adjust 100K pot to give 125 Hz for 4109 or 250 Hz for 4111. Successive stages of SN7404 inverter provide required sharpening of pulse.A1 is positive-starting MVBR.—R. W.
