Abstract
A signal sampling circuit is disclosed which accommodates itself to operation during the presence of high noise levels encountered, for example, when attempting to monitor and control, and thus optimize, the functioning of an internal combustion engine. Noise detection means is provided for detecting the presence or absence of noise pulses during either a request for a signal sample or during a signal sampling period. When the noise detector indicates the presence of noise during the request or during the sampling period, the derived information is disregarded and either reread during the next, noise-free period or is resampled shortly after the sampling interval in which the discarded information was obtained.
