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 clock system includes a phase locked loop, a phase divider, and a control module. The phase locked loop (PLL) produces a plurality of phase-offset output oscillations. The phase divider generates a clock signal from one or more of the plurality of phase-offset output oscillations based on a phase divider control signal. The control module generates the phase divider control signal based on a desired setting for the clock signal.

摘要： A digital phase locked loop (PLL) includes a digital phase detector, a digital loop filter, a digitally controlled oscillation module, and a variable feedback divider. The digital phase detector is coupled to produce a difference signal based on a phase difference between a reference oscillation and a feedback oscillation. The digital loop filter is coupled to process the difference signal to produce a control signal. The digitally controlled oscillation module is coupled to generate an output oscillation based on the control signal. The variable feedback divider is coupled to produce the feedback oscillation from the output oscillation based on a divider value and a controlled variable delay.

摘要： A method for signal strength detection begins by comparing a signal strength representation of a signal with a signal strength representation of a reference signal. The method continues by adjusting, when the signal strength representation of the signal compares unfavorably with the signal strength representation of the reference signal, at least one of the signal strength representation of the signal and the signal strength representation of the reference signal until the signal strength representation of the signal compares favorably with the signal strength representation of the reference signal. The method continues by determining signal strength of the signal based on the adjusting of the signal strength representation of the signal and signal strength of the reference signal.
