Abstract : With the device described it is possible to measure the mutual phase position of two signals with special consideration of the propagation of VLF and LF waves. The minimum operating input amplitude is selectable. The phase is indicated digitally and is independent on the amplitude and the frequency between 100 Hz and 100 kHz. The device is intended for battery operation (minimum current consumption). The errors resulting from the principle of measurement are calculated and methods are described to restrict them to a minimum. In addition to the block circuit diagram detailed connection diagrams are given. (Author)
