Abstract
According to various embodiments, a system for acoustic to electronic transduction is disclosed. The system includes a transducing medium configured to convert a received acoustic signal into a transduced electronic signal when a voltage is applied. The system further includes a high-pass filter coupled to the transducing medium, the high-pass filter configured to isolate the transduced signal from the applied voltage.
Claims17
A system for acoustic to electronic transduction, comprising:
- a transducing medium having an ionized gas and a pair of electrodes with a distance between the pair of electrodes being less than half a wavelength of an acoustic signal received by the transducing medium, the transducing medium configured to convert the received acoustic signal into a transduced electronic signal based on an electrical resistivity of the transducing medium when a fixed direct current (DC) voltage is applied to the transducing medium;
- and
- a high-pass filter coupled to the transducing medium, the high-pass filter configured to isolate the transduced electronic signal from the applied fixed DC voltage.
A method for acoustic to electronic transduction, comprising:
- applying a fixed DC voltage to a transducing medium having an ionized gas and a pair of electrodes with a distance between the pair of electrodes being less than half a wavelength of an acoustic signal received by the transducing medium to convert the acoustic signal into a transduced electronic signal based on an electrical resistivity of the transducing medium;
- and
- high-pass filtering the electronic signal to isolate the transduced electronic signal from the applied fixed DC voltage.
A system for acoustic to electronic transduction, comprising:
- a transducing medium having a pair of electrodes immersed in an ionized gas with a distance between the pair of electrodes being less than half a wavelength of an acoustic signal received by the transducing medium, the transducing medium configured to convert the received acoustic signal into a transduced electronic signal based on an electrical resistivity of the transducing medium when a fixed direct current (DC) voltage is applied to the transducing medium, the electronic signal being derived from a potential difference between the pair of electrodes when the fixed DC voltage is applied, the potential difference being caused by pressure perturbation of an acoustic wave which changes the electric resistivity of the transducing medium to create the potential difference between the pair of electrodes;
- and
- a high-pass filter coupled to the transducing medium, the high-pass filter configured to isolate the transduced electronic signal from the applied fixed DC voltage.
