Abstract
Abstract Two signal generators, such as sonic logging transmitters, are actuated sequentially by a circuit which includes an oscillator and a pulse generator. The delay between the actuations is established by a comparison circuit which compares counts registered on a counter with a preset count. Circuit means are also provided for converting received analog signals to digital form and recording the digital signals.
