Abstract: A circuit assembly for processing an electrical signal of a microphone is provided. The microphone has an inherent impedance. The circuit assembly comprises an impedance circuit, a signal processing unit, a first electrical signal path, and a second electrical signal path. The first electrical signal path is coupleable to a first electrical output of the microphone and is furthermore coupled to a first input of the signal processing unit. The second electrical signal path is coupleable to a second electrical output of the microphone and is furthermore coupled to a second input of the signal processing unit via the impedance circuit. An impedance value of the impedance circuit is selected based on an impedance value of the inherent impedance of the microphone.

Abstract: Apparatus and method to detect one or more keys of a mobile wireless electronic device that have received an activating input, e.g., have been pressed, interrogates simultaneously several keys of a group of keys to reduce time required to detect which of the keys is pushed to provide inputs to the electronic device. The keys are arranged in a two dimensional matrix that facilitates organized interrogation of the keys. Resistors are used in providing a decoupling effect with respect to the antenna function of the wireless electronic device.
