RECEIVING SYSTEM OF TELEMETERING SIGNAL ABSTRACT OF THE DISCLOSURE In a telemeter system using a measuring probe for radiating a sound pulse signal, the pulse spacing of which corresponds to information to be measured, such as temperature or salinity of various depths in the ocean water, in order to prevent the echo noise signal, there is provided an improved receiving system which comprises a one-bit delay circuit, a pair of integrating circuits, a pulse generator and a gate. One of the integrating circuits is controlled by the signal as received, and the other is controlled by a one-bit delayed signal derived from the received signal. The pulse generator generates a pulse signal having a predetermined time duration at a predetermined level of the output from the integrating circuit, and that pulse drives the gate so that the receiving operation is controlled and an echo present outside of the period corresponding to the above time duration can be prevented.
