    摘要: A radio frequency (RF) signal is received in a receiver, and various counts based on information from the signal can be obtained. Counts of a number of samples of the RF signal exceeding first and second thresholds can be accumulated during an accumulation window. From the first of these counts, it can be determined if the count exceeds a first metric corresponding to a first predetermined count value, and if so, a gain of an RF gain element can be reduced. From the second of these counts it can be determined if this count exceeds a second metric corresponding to a second predetermined count value, and if not, the gain can be increased.

    摘要: A receiver includes a mixing module for mixing an input signal by at least one mixing sequence to produce a mixed signal. The mixed signal is filtered to produce a first filtered signal. A first downsampler downsamples the first filtered signal to produce a first decimated signal, wherein the decimation period is not a multiple of the mixing period.

    摘要: A radio receiver, optionally used in conjunction with a handheld audio system, includes a radio stage for processing a received radio signal into an audio signal. An audio stage produces an audio output, based on the audio signal. An overload monitor detects an overload condition in the radio stage and generates an overload signal in response to the detected overload condition. A controller controls the audio output in response to the overload signal.

    摘要: In one embodiment, a receiver front end circuit can receive and process multiple radio frequency (RF) signals and output downconverted signals corresponding to these signals. In turn, multiple signal processors can be coupled to this front end. Specifically, a first signal processor can receive and process the downconverted signals to output a first signal obtained from content of a first RF signal, and a second signal processor can receive and process the downconverted signals to output a second signal obtained from content of a second RF signal. In addition, the apparatus may include a detection circuit coupled to the receiver front end circuit to detect presence of at least the second signal and enable the second signal processor responsive to the detected presence.

    摘要: A method for mitigating interference from a switched-mode power supply begins by comparing a channel of interest of a plurality of channels with a switching rate of a switch-mode power supply. The method continues when the channel of interest compares unfavorably to the switching rate by adjusting the switching rate of the switch-mode power supply until the channel of interest compares favorably to the switching rate.

    摘要: A system on a chip integrated circuit includes a first in-phase digital submodule and a first quadrature phase digital submodule such that the first in-phase digital submodule and the first quadrature phase digital submodule are operable to produce at least one output signal based on at least one input signal. A digital clock generator generates a first in-phase digital clock signal having a plurality of first in-phase digital clock cycles over a predetermined period and a first quadrature phase digital clock signal having a plurality of first quadrature phase digital clock cycles over the predetermined period. The plurality of first in-phase digital clock cycles are substantially interleaved with the plurality of first quadrature phase digital clock cycles over the predetermined period.
