摘要
FM and AM receivers in car environments require a noise blanker circuit or method to reduce the audible disturbances generated by impulse noise, such as ignition noise, in the audio signal. The invention proposes a combination of time-domain and frequency-domain processing to reduce the audible distortion. The time-domain processing interpolates the signal during the impulse noise bursts, and the frequency-domain processing disperses the remaining signal distortion over time, or relocates it to positions in time where it is attenuated by a windowing technique.
