Abstract
An ambulatory recorder which features an enhance technique for sampling. The ambulatory recorder has a programmable number of channels, each channel having a programmable sampling frequency rate. The multi channel ambulatory recorder is fashioned so as to sample and records data only from each channel as desired at the frequency as desired. The recorder examines the frequencies on the channels for which data is to be sampled and recorded, and selects a common tick frequency for the microprocessor to awaken, sample and sleep again.
