DCC - Zero Stretching Simulator

Published:2013/6/18 3:55:00 Author:muriel | Keyword: DCC - Zero Stretching Simulator | From:SeekIC

This circuit is designed to simulate the 'Zero Stretching' function of Digital Command Control systems used by model railroads. This circuit was used drive the booster while testing the operation of block occupancy detectors and DCC signal failure circuits while in the zero stretching mode. The parts values have been calculated to give the maximum stretching length and ratio allowed for DCC systems. Complimentary outputs, A and B, are provided in order to drive the booster's output polarity stretched in both directions.
