Abstract:
An apparatus for monitoring one of multiple channels, comprising:counting means for increasing a first count value when an up mode is selected and for decreasing the count value when a down mode is selected, wherein the count value corresponds to a channel number of the multiple channels;mode selecting means for selecting one of the up and the down modes;means for inputting a channel number;means for generating a second count value corresponding to the channel number from the inputting means and a write-enable signal;source selecting means for selecting one of the count values from the counting means and from the generating means;signal generating means for generating a channel selecting signal corresponding to the selected count value;converting means for extracting data from a channel depicted by the channel selecting signal and converting transmission rate of the data; andanalyzing means for monitoring the data from the converting means to check whether or not the data is transferred properly.
