The significance of the production of the integrated microelectronic pulse shaper, which is used in railway automation and telemechanics systems, plays an important role in ensuring the safety of train traffic, and can completely replace track and pendulum transmitters, and the electrical circuits of the device are presented based on research and the principles of using microelectronic devices in the production process. It has been experimentally proven that the integrated microelectronic pulse shaper works without interfering with each other in the production of parallel codes. Values calculated on the basis of the Bayesian method of diagnosing the reliable operation of the device are presented. These values were verified in the experiment by connecting the device to the actual operating system at a real station.
