1. A circuitry for processing an analog signal, the circuitry being configured to:
generate a sample control signal depending on an energy level of the analog signal in at least one predefined frequency band,
control a sampling rate for sampling the analog signal based on the generated sample control signal, and
synchronize the analog signal and the sample control signal to compensate for a delay between the analog signal and the sample control signal.
