AN IMPROVED SYSTEM FOR RECORDING THE PHASE AND AMPLITUDE OF VLF AND LF STANDARD FREQUENCY TRANSMISSIONS,

Abstract

An improved system for recording the relative phase and amplitude of frequency stabilized LF and VLF transmissions is described. The versatility and ease of maintenance of the system has been greatly improved by the use of modular construction and plug-in printed circuit boards. This type of construction will enable the system to meet any anticipated requirements for coherent measurements in the LF and VLF region. The very low power dissipation of the transistor circuits used increases the reliability and long term stability of the coherent circuits. (Author)
