Abstract
Abstract 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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
203 words
A method for analysis of binary signal pulses having respective pulse durations and pulse states, which comprises the steps of: measuring the duration of each signal pulse by counting units of time in a counter while receiving the pulses; determining the pulse state by means of a state memory; resetting the counter at each pulse state change transferring as signal bytes the counter-reading and respective pulse state reached into a fifo memory at a further pulse state change; resetting and restarting the counter; transferring the signal bytes to a signal list in a microprocessor; taking the signal bytes from the signal list for retransmission of signals and loading the signal bytes into a register; controlling a programmable counter on the basis of the counter-reading of the signal bytes; determining the respective duration of the signal pulses to be retransmitted on the basis of the respective counter-reading; determining the state of the respective pulses to be retransmitted by means of the state bit of the respective signal bytes; forming distortion tables in an associate memory; addressing the distortion tables by means of the counter information of the signal bytes deposited in the signal list; and reading the signal distortion values from said distortion tables.

Claim 3
Dependent Claim
18 words
Method according to claim 1, which comprises depositing the signal distortion values in the tables as percentage values.
Claim 4
Dependent Claim
15 words
Method according to claim 1, which comprises displaying the read-out distortion values as bar indicators.
Claim 5
Dependent Claim
51 words
Method according to claim 1, which comprises forming further tables which are addressed by signal bytes from the signal list, forming auxiliary values; and performing a determination of the start signals and other signals and an analysis of the information content of said binary signals by means of the auxiliary values.
Claim 6
Dependent Claim
16 words
Method according to claim 1, which comprises detecting spikes by evaluating the read-out signal distortion values.
Claim 7
Dependent Claim
28 words
Method according to claim 1, which comprises calling information from transfer lists for the synthesis of signal; and transferring the information as signal bytes into the signal list.
