摘要： To prevent that the noise occurs at timing switching between PCM data and DSD data by a simple configuration.An AV receiver 1 includes a mute circuit 5 that mutes output from a DAC 4, a detection circuit 6 that detects that a digital audio signal is zero data and supplies a detection signal, a microcomputer 2 that supplies a control signal at timing switching from PCM data to DSD data before switches from PCM mode that the DAC 4 converts PCM data into an analog audio signal to DSD mode that the DAC 4 converts DSD data into the analog audio signal, and an AND circuit 7 that activates the mute circuit 5 in case that the detection signal from the detection circuit 6 and the control signal from the microcomputer 2 are supplied.

摘要： Techniques for mute pattern injection for a pulse-density modulation microphone are described. In one or more implementations, a pulse-density modulation (PDM) microphone includes a transducer that receives a pressure wave and produces an analog signal that represents the pressure wave, an analog-to-digital converter (ADC) that receives the analog signal from the transducer and converts the analog signal into a digital PDM signal. The PDM microphone also includes a pattern generator that generates a digital mute signal, a controller that outputs control signals, and a multiplexer that receives the control signals, the digital mute signal, and the digital PDM signal. The multiplexer transmits the digital mute signal or the digital PDM signal, responsive to the control signals.

摘要： A method for testing a power amplifier assembled in a gateway connected to a service provider network includes remotely testing the radio of the gateway. The method configures the gateway to perform a first baseline receive noise measurement and compare it to a second receiver noise measurement. The power amplifier is determined to be in a fault condition if the second receiver noise measurement is greater than the baseline receiver noise measurement.

摘要： A squelch detector receives a first input signal, a second input signal, a first reference voltage and a second reference voltage. The first input signal and the second input signal are collaboratively defined as a differential input signal pair. The difference between the first reference voltage and the second reference voltage is defined as a squelch threshold. According to the squelch threshold, the squelch detector generates a detected signal to indicate whether the differential input signal pair is valid or not.

摘要： An approach is provided that receives an audio request from a request source while an information handling machine, such as a computer system, is in a muted state. The request source is compared with a list of one more un-mute sources stored in a memory. If the comparison reveals that the request source is included in the list of un-mute sources, then the audio request is audibly played.

摘要： A system and method used for controlling an attenuator in a two-way communication device (100, 200) includes the steps of measuring (211) a relative signal strength indication (RSSI) at the input of the two-way communications device. The RSSI measurement is then compared (213, 217, 223) to both at least one predetermined interference threshold value (T1, T2, T3) and a selective squelch state (219, 225) for determining whether to switch an in-line attenuator to the input of the two-way communications device. The invention provides a method by which an attenuator may be used only when interference is present without it being continually switched in-line to cause signal degradation.
