Definitions

  • the microphone 1 is of a type which is suited to be attached to an appropriate place on a body, in regard to the type of body sound to be monitored. Various microphone types are of interest, however the microphone type itself does not constitute any part of the present invention.
  • the signals captured by the microphone l pass to a microphone preamplifier 2 which either may be built together with a microphone in order to shorten the conductor path between microphone and preamplifier, with regard to the fact that the weak signals are to a large degree exposed to degradation from noise, or the preamplifier 2 can be physically built together with the units following thereafter.
  • the sampled and digitized signal delivered by the converter 8 is passed to a digital processing equipment 9, and it is of course possible to include herein digital filters which are able to conduct the same type of filtering as basically executed in circuit 4. For the rest, the circuit is of the same type as shown in fig. 1.
  • Fig. 3 shows, still in the form of a block diagram, a more detailed representation of a circuit which is a combination of the versions shown in fig. 1 and fig. 2. Both the automatic gain control unit 3 and the digital equipment 8,
