Abstract

A method and apparatus for measuring a predetermined parameter having a known relation to the transit time of movement of an energy wave through a medium including a transmitter (2) and receiver (3) for transmitting and receiving the cyclically-repeating energy wave. The cyclically-repeating energy wave is an electromagnetic carrier wave amplitude modulated by a cyclically-repeating electromagnet modulating wave having a fiducial point 'Zero Crossover' which is utilized to change the frequency of the modulating wave such that the number of received demodulated waves is a whole integer
