    摘要: The invention relates to a system and method for attenuating harmonics in output signals. In the system, an electronic circuit for reducing harmonics of an output signal from a power amplifier in a transmission circuit for a wireless communication device is provided. The circuit comprises: a printed circuit board (PCB); a power amplifier for generating an output signal; and a circuit implemented on the PCB connected to an output terminal of the power amplifier for the output signal. The circuit comprises a first filtering stage; a delay element; and a harmonic filter. The delay element is located between the harmonic filter and the output terminal and the delay element provides a timing delay in the output signal through at least one 0 ohm-rated component. Also, the harmonic filter is a low pass filter having a frequency cut-off point that attenuates first order harmonics of the output signal.

    摘要: A peripheral for an electronic device having a speaker is provided. The peripheral includes an input device for placement proximal to the speaker for receiving audio information from the speaker. The peripheral includes an output device connected to the input device that is positioned distal from the input device and away from electromagnetic signals generated by the device. The output device presents the audio information to a hearing aid proximal to the output device. The output device is positioned at a distance such that the electromagnetic signals experienced by the input device is less than the signals experienced by the hearing aid. As a result, deleterious effects of signals otherwise experienced by the hearing aid are reduced.
