The measurement of the depth of a sonar array using a modified counting technique for the demodulation and decoding of frequency modulated instrumentation signals is presented. A data dependent overflowing counter feeds demodulated data into a Programmable Read Only Memory based lookup table. Controlled, repeated counter overflows maximise the information content of the data. The system resolution is thus considerably increased with no effect on accuracy or component count. Frequency discriminating circuits are superfluous with this technique. Originator-supplied keywords include Depth finding, and Pressure sensors.
