MUMBAI, India, Sept. 12 -- Intellectual Property India has published a patent application (202517075412 A) filed by International Business Machines Corporation, Armonk, U.S.A., on Aug. 7, for 'separable, intelligible, single channel voice communication.'
Inventor(s) include Chantz, Hyman, David; Lynch, Robert; and Swift, Elijah.
The application for the patent was published on Sept. 12, under issue no. 37/2025.
According to the abstract released by the Intellectual Property India: "The method provides for separable subchannels sharing a communication channel. A processor receives input of a user setting a transmitter device to a first of at least two subchannels of a communication channel in which the first subchannel comprises a first portion of a bandwidth of the communication channel. The processor receives an audio signal as input to the transmitter device. The processor converts a time-series waveform of the audio signal into a frequency-series waveform. The processor determines that the transmitter device is set to the first subchannel. In response to determining the device is set to the first channel, the processor filters the frequency- series waveform through a series of steep shoulder digital bandpass filters set to transmit through the first portion of the bandwidth, and the processor transmits the audio signal as the filtered frequency-series waveform."
The patent application was internationally filed on Feb. 22, 2024, under International application No.PCT/EP2024/054509.
