ABSTRACT:
An Audio Feedback Impedance Comparison Device to audibly express Impedance differences between/amongst components, circuits, materials, substances etc., to make use of the aural sense, while relieving eye, neck and mental strain, as well as reduce probe time. This is achieved by allowing simultaneous yet focused attention to be paid to all aspects of an impedance probe, i.e. hand-eye coordination of probe positioning, while aurally monitoring the feedback, instead of the common practices/methods where eyes have to be re-focused on visual feedback devices. The use of an alternating signal allows “through” comparison, where multiple components some of which are impervious to static signal, contribute to overall impedance. The device can be used to inject and/or detect/trace the presence of an audio signal in an active circuit. With the aid of transducers, this Device may be used with other forms of energy.
