Patent number: 11017759Abstract: A method may include receiving a user trigger signal indicating a user desire to update characteristics of an adaptive filter, receiving an error microphone signal indicative of the output of the transducer and the ambient audio sounds at the transducer, wherein the transducer reproduces both a source audio signal for playback to a listener and an anti-noise signal for countering the effects of ambient audio sounds in an acoustic output of the transducer, implementing the adaptive filter having a response that generates the anti-noise signal to reduce the presence of the ambient audio sounds in the error microphone signal, determining an acoustic coupling of the transducer to an error microphone for producing the error microphone signal, and responsive to a change in the acoustic coupling, prompting a user to assert the user trigger signal to indicate user desire to update characteristics of the adaptive filter.Type: GrantFiled: June 5, 2020Date of Patent: May 25, 2021Assignee: Cirrus Logic, Inc.Inventors: K. Joshua Bodon, Jon D. Hendrix, Brian Thornock, Aaron Treptow, Shahram Tadayon

Patent number: 8315587Abstract: In one implementation, a receiver may have an analog front end with an amplifier to receive a radio frequency (RF) signal and a mixer to downconvert the signal to a baseband signal. Then, a demodulator may receive the baseband signal and obtain an audio signal therefrom. Still further, a controller may be coupled to receive a control signal corresponding to a variable impedance level, and control a local oscillator coupled to the mixer responsive to the control signal. The variable impedance may be controlled by a user to tune to the channel.Type: GrantFiled: August 29, 2008Date of Patent: November 20, 2012Assignee: Silicon Laboratories Inc.Inventors: Shahram Tadayon, Wade Robert Gillham, Peter J. Vancorenland, Daniel Mark Thompson
