Electronic stethoscope
First Claim
1. An electronic stethoscope comprising:
- a receiver adapted for receiving an external audio signal attributed to a human body part;
a filter unit coupled electrically to said receiver for receiving and filtering the audio signal received by said receiver so as to output a set of target signals associated with the audio signal, each of which has a frequency within a specific frequency band;
an analog-to-digital converter coupled electrically to said filter unit for converting the set of the target signals into a set of digital signals;
an operating unit operable so as to generate an input mode signal corresponding to a selected operating mode for selecting one of the digital signals;
a processor coupled electrically to said analog-to-digital converter and said operating unit for receiving the set of digital signals and the input mode signal therefrom, said processor processing and outputting one of the digital signals that is selected according to the input mode signal; and
an audio playback unit coupled electrically to said processor for receiving and reproducing output of said processor.

Abstract
In an electronic stethoscope, a filter unit receives and filters an audio signal attributed to a human body part and received by a receiver so as to output a set of target signals associated with the audio signal. The target signals have frequencies within specific frequency bands and are converted into a set of digital signals. An operating unit is operable so as to generate an input mode signal corresponding to a selected operating mode for selecting one of the digital signals. A processor receives the set of digital signals and the input mode signal, and processes and outputs one of the digital signals that is selected according to the input mode signal. An audio playback unit receives and reproduces output of the processor.
