An electronic device may be operable to sample a signal during an analog-to-digital conversion using an analog-to-digital converter in the electronic device, and the signal may comprise a wide bandwidth and a plurality of channels. The electronic device may adaptively change a sample rate of the sampling to move aliasing out of a region of one or more desired channels of the plurality of channels. The electronic device may change the sample rate using a variable oscillator in the electronic device. The change of the sample rate may comprise, for example, increasing or decreasing the sample rate by a particular percentage. In response to the change of the sample rate, the electronic device may perform, using a variable rate interpolator in the electronic device, variable rate interpolation. The variable rate interpolator may comprise, for example, a finite impulse response filter.

Embodiments disclose systems and methods for testing and determining outages of communication systems. A server can receive signal-reception-related information from set-top boxes (STBs) in a particular geographical region, where a STB: receives signals having a predefined pattern, generates a comparison of the predefined pattern to reference patterns stored on the STB, generates the signal-reception-related information based on the comparison, and sends the signal-reception-related information. The server can determine an outage status for the particular geographical region based on the signal-reception-related information. The server can generate an output based on the outage status. The output is configured to provide information related to the outage status of the particular geographical region and information for possible responses related to the outage status. The server can send the output.
