Digital Adaptive Feedforward Harmonic Distortion Compensation For Digitally Controlled Power Stage

View page
US Patent:
7907664, Mar 15, 2011
Filed:
Dec 7, 2009
Appl. No.:
12/632323
Inventors:
Zukui Song - Waltham MA, US
Michael Determan - Brighton MA, US
Assignee:
Sigmatel, Inc. - Austin TX
International Classification:
H03K 7/08
US Classification:
375238, 381 28, 381120, 330297, 330123, 330199, 332109, 332106
Abstract:
Systems and method to compress digital video based on human factors expressed as a desirability score are provided. A particular method includes passing a digital input signal through a pulse-width modulator and passing an output of the pulse-width modulator through a power switching device. An output of the power switching device has a plurality of pulses. The method includes receiving the output of the power switching device at a first input of a comparator and receiving a reference voltage at a second input of the comparator. The method includes determining a net signal based on an output of the comparator and determining a timing error signal based on the net signal and the digital input signal. The method also includes adjusting the digital input signal to compensate for harmonic distortion based at least in part on the timing error signal.

Digital Adaptive Feedforward Harmonic Distortion Compensation For Digitally Controlled Power Stage

View page
US Patent:
20060034365, Feb 16, 2006
Filed:
Aug 5, 2005
Appl. No.:
11/198383
Inventors:
Zukui Song - Waltham MA, US
Michael Determan - Brighton MA, US
International Classification:
H03K 7/08
US Classification:
375238000
Abstract:
A digital timing read back and an adaptive feedforward compensation algorithm to reduce harmonic distortion is disclosed. More specifically, the approach generates harmonic components digitally with the same magnitude but at an opposite phase to the output harmonic distortion. An anti-distortion signal is generated and added to the input signal. The magnitude and phase of the harmonic distortion change with the modulation level or index and the frequency of the input signal. In addition, the harmonic distortion level varies significantly with different timing error statistics in different power devices. The inventive method takes the modulation level or index, the frequency of the input signal and the timing error statistics acquired through a digital read back circuit as input variables to determine the magnitude and phase of the anti-distortion signal.

Signal Component Estimation Using Coherence

US Patent:
20220199105, Jun 23, 2022
Filed:
Apr 30, 2020
Appl. No.:
17/607649
Inventors:
- Framingham MA, US
Zukui Song - Wellesley MA, US
Cristian Marius Hera - Lancaster MA, US
Davis Y. Pan - Arlington MA, US
Assignee:
Bose Corporation - Framingham MA
International Classification:
G10L 25/21
G10L 21/0232
H04R 3/04
Abstract:
Systems, methods, and machine-readable storage devices that receive an input signal representing audio captured using a microphone. The input signal includes portions that represent acoustic output from one or more audio sources, and a portion that represents other acoustic energy in the environment. A frequency domain representation of the input signal is iteratively modified to substantially reduce effects due to all but a selected one of the portions, from which an estimate of the power spectral density, PSD, of the selected portion is determined. Based upon the estimated PSD a noise or echo component is reduced, or a replacement noise is provided. The iterative modification involves a diagonalization of the cross-spectral density matrix to remove content coherent with a first audio input from the auto and cross-spectra of other signals.

Noise Estimation Using Coherence

US Patent:
20200186115, Jun 11, 2020
Filed:
Feb 19, 2020
Appl. No.:
16/794765
Inventors:
- Framingham MA, US
Zukui Song - Wellesley MA, US
David J. Warkentin - Boston MA, US
Assignee:
Bose Corporation - Framingham MA
International Classification:
H03G 3/32
H03G 5/16
G10L 21/034
G06F 17/16
H03G 3/30
H04R 29/00
Abstract:
The technology described herein can be embodied in a method for estimating a power spectral density of noise, the method including receiving an input signal representing audio captured using a microphone. The input signal includes a first portion that represents acoustic outputs from two or more audio sources, and a second portion that represents a noise component. The method also includes iteratively modifying a frequency domain representation of the input signal, such that the modified frequency domain representation represents a portion of the input signal in which effects due to the first portion are substantially reduced. The method further includes determining, from the modified frequency domain representation, an estimate of a power spectral density of the noise, and generating a control signal configured to adjust one or more gains of an acoustic transducer. The control signal is generated based on the estimate of the power spectral density of the noise.

16/552191
Inventors:
- Framingham MA, US
Zukui Song - Wellesley MA, US
Shiufun Cheung - Lexington MA, US
Eric J. Freeman - Sutton MA, US
International Classification:
G06F 17/28
G10L 15/18
G06F 16/9032
Abstract:
A method of operating a situationally aware speaker associated with a virtual personal assistant (VPA) service provider that comprises receiving an indication of at least one parameter of an environment proximate the situationally aware speaker, and delivering the response to the vocal query to the user formatted as speech through an audio output of the situationally aware speaker, at least one audio parameter of the response set based on the indication of the at least one parameter.

Dynamic Sound Adjustment Based On Noise Floor Estimate

View page
US Patent:
20190341020, Nov 7, 2019
Filed:
Jul 16, 2019
Appl. No.:
16/512464
Inventors:
- Framingham MA, US
Zukui Song - Wellesley MA, US
International Classification:
G10K 11/178
G10L 21/0208
G10L 21/0216
Abstract:
The technology described in this document can be embodied in a method that includes receiving a plurality of representations of the signal corresponding to samples of the signal within a frame of predetermined time duration, and estimating a power spectral density (PSD) for each of a plurality of frequency bins. The PSD for a particular frequency bin is estimated based on a smoothing parameter calculated from a noise estimate for the particular frequency bin as obtained from samples corresponding to a preceding frame. The method also includes generating, based on the PSD for each of the plurality of frequency bins, an estimate of the steady-state noise floor, and computing a measure of spectral flatness associated with the samples within the frame. The method also includes determining that the measure of spectral flatness satisfies a threshold condition, and in response, computing an updated estimate of the steady-state noise floor.
