摘要： The invention provides an arrangement for time correlating a computer's internal information with its input and output signals. The internal information is stored in a storage device along with time data indicative of the time at which the internal information was read. This time data is used to correlate the internal information, when read from storage, with the input and output signals. The invention also provides a more general arrangement for producing logic signals. Data for producing logic signals are stored in a memory. This data includes a transition time and a corresponding logic level after the transition. Logic signals are generated and "forced" to the logic level called for by the data read from memory. This allows logic signals to be produced from little data. This general scheme is applied to an arrangement for recording and reproducing digital and analogue signals. Digital data is recorded in memory and "reconstructed" using a single, common, clock is used for A/D and D/A converting to insure synchronism over a long period of time.
