Claims
- 1. Apparatus for displaying a digital signal representing a sequence of data states, the apparatus comprising:
- input means coupled to receive the digital signal for producing output signals representative of the data states of the digital signal received thereby;
- qualifier means coupled to receive the output signals from said input means for producing an output signal in response to a data state received thereby attaining a selected qualifying state condition;
- selection means coupled to said qualifier means for providing a signal representative of the qualifying state condition;
- storage means having a first input coupled to receive the output signals from said input means and having a second input for receiving the output signal from said qualifier means for storing signals representative of the signals appearing on the first input in response to a signal appearing on the second input;
- format control means for receiving signals representative of selectable assignments of sets of contiguous bits of each data state to logical fields, representative of a selected concatenation of the logical fields, and representative of radicies selected for the respective logical fields for producing therefrom an output indicative of the signals received thereby;
- converter means coupled to said storage means for producing a formated signal representing the stored signals of said storage means formatted in response to the output of said format control means; and
- display means for providing a visual display of the formatted signal.
- 2. A method for displaying selected data states of a digital signal in logical fields, the method comprising the steps of:
- selecting a qualifying state condition;
- detecting a data state satisfying the selected qualifying state condition;
- storing signals representative of digital signals having a predetermined relationship to the detected data state;
- selectively assigning bits of the stored signals to logical fields; and
- displaying representations of the assigned bits in a format distinguishing the selected logical fields.
- 3. A method as in claim 2 further comprising the steps of:
- selecting independent radices for each of the logical fields;
- converting the bits assigned to each logical field to a variable in accordance with the radii selected therefor; and
- displaying the variables representative of the logical fields.
- 4. A method as in claim 3 further comprising the steps of:
- selecting a concatenation of the logical fields; and
- displaying the variables in a format concatenating the logical fields as selected.
