A Multi‐Channel Delay Unit

Details are given for the construction of a time delay circuit of particular value for physiological laboratories using oscillographs for studying action potentials of the nervous system. It permits timing separate events at any interval in a cycle of operation determined by a master oscillator. The...

Description
Summary:Details are given for the construction of a time delay circuit of particular value for physiological laboratories using oscillographs for studying action potentials of the nervous system. It permits timing separate events at any interval in a cycle of operation determined by a master oscillator. The operation of the circuit depends on the grid extinction of a thyratron operating at low current.
