    摘要： Method for analyzing and synthesizing pulses using a first pulse state memory for storing the pulse state connected to a pulse edge detector for detecting a pulse change of state, the latter connected to the reset pin of a pulse counter driven by a clock; a first-in-first-out memory connected to the counter for receiving the counter content for each pulse, and a microprocessor connected to the first-in-first-out memory output, having a signal pulse list for storing for each pulse its state and pulse length measured in clock counts. Two or more associate memories are provided for storing clock count of any 0-state pulse and any 1-state pulse, and a pulse display connected to each associate memory to display any 0-state pulse and any 1-state pulse as a percentage of the total pulse period To.
