Abstract

The command signal appears with a phase shift in relation to the instant of a periodic information signal reception. During each period voltages, which are functions of the peak value of the voltage generated during a previous period, are stored. The stored voltages are set to zero during a preset time calculated from the instant of the previous voltage resetting to zero. Further voltages are generated as periodic functions of time not exceeding the previous voltage period. The stored voltages and the additional voltages are compared in pairs, and a coincidence signal is generated with a phase shift. A synchronous signal is allocated to the phase-shifted signal. One signal of this group is selected to trigger the command signal.
