Abstract
Abstract The data storing method includes the steps of: (a) receiving a data encoded signal; (b) sampling the received data encoded signal at a first sampling rate; (c) counting the number of consecutive samples at a first logic level; (d) storing the number of samples counted in step (c) in a first portion of a memory template; (e) counting the number of consecutive samples at a second logic level; (f) comparing the number of samples counted in step (e) to a threshold value; (g) changing the sampling rate at which the received data encoded signal is sampled and counting the number of consecutive samples at the second logic level if the number of samples counted in step (e) exceeds the threshold value; and (h) storing in the memory template, the number of samples counted in step (e) if the threshold was not exceeded, or the number of samples counted in step (g) if the threshold value was exceeded. The apparatus includes a processor programmed to perform the above steps. The method is well-suited for use in a trainable transmitter.
