Abstract: An apparatus that can be configured for various functions such as a digital oscilloscope, logic analyzer or frequency analyzer is disclosed. The apparatus includes a symbol generator, a multi-symbol FSM, and a controller. The symbol generator generates an ordered sequence of symbols from an ordered sequence of digital values. The symbol generator generates one symbol corresponding to each of the digital values. The digital values have a greater number of possible values than the symbols. The controller causes the multi-symbol FSM to search for a pattern in the sequence of symbols that identifies a corresponding pattern in the sequence of digital values. A portion of the digital sequence is then displayed based on the location of the pattern in the sequence of symbols.

Abstract: An apparatus that can be configured for various functions such as a digital oscilloscope, logic analyzer or frequency analyzer is disclosed. The apparatus includes a symbol generator, an FSM, and a controller. The symbol generator generates an ordered sequence of symbols from an analog input signal. The symbols have a number of states that is less than or equal to 16. The controller causes the FSM to search for a pattern in the sequence of symbols that identifies a corresponding pattern in the analog signal. A portion of a digital sequence generated from the analog signal is then displayed based on the location of the pattern in the sequence of symbols.

To adjust a bit rate of the sending signal, the serial and parallel converter(U3) is supplied with a clock and parallel load signals and produces a continuous serial bit stream data in accordance with 1 bit output by a clock input after latching A/D converted signals to the converter.
