Claim 1
Independent Claim
205 words
Process for measurement of distortion in transmission systems which transmit binary coded data in parallel form on parallel output lines from a data source, comprising the steps of: setting a reference point at and actuating a first timing member at the first appearance of an impulse on one of the parallel output lines, producing an output from said first timing member during an interval corresponding to 0.5 times the theoretical character duration, an edge of said first timing member output being used as a scanning mark, routing all impulses appearing on the output lines during said interval to an indicating device and there indicating their time relation to said referenced point, actuating a second timing member upon the first appearance of an impulse on one of the output lines, producing an output from second timing member upon the first appearance of an impulse on one of the output lines after said interval has elapsed, indicating the time position of said first impulse following said interval relative to said reference point and switching said second timing member and said indicating device to an output condition after 1.5 times the theoretical duration of a character on the failure of an impulse to appear on an output line.
Claim 2
Dependent Claim

Process for measurement of distortion in transmission systems which transmit binary coded data in parallel form on parallel output lines from a data source, comprising the steps of: setting a reference point at and actuating a first timing member at the first appearance of an impulse on one of the parallel output lines, producing an output from said first timing member during an interval corresponding to 0.5 times the theoretical character duration, an edge of said first timing member output being used as a scanning mark, routing all impulses appearing on the output lines during said interval to an indicating device and there indicating their time relation to said referenced point, actuating a second timing member upon the first appearance of an impulse on one of the output lines, producing an output from second timing member upon the first appearance of an impulse on one of the output lines after said interval has elapsed, indicating the time position of said first impulse following said interval relative to said reference point and switching said second timing member and said indicating device to an output condition after 1.5 times the theoretical duration of a character on the failure of an impulse to appear on an output line.
Claim 3
Dependent Claim
30 words
The process defined in claim 1 comprising the additional step of: producing a scanning pulse on a separate output line for switching said first timing member to a quiescent state.
Claim 4
Dependent Claim
33 words
The process defined in claim 2 wherein only the maximum value of the scattering width of identifying time points and the maximum value of the scattering width of the character duration is indicated.
Claim 5
Dependent Claim
53 words
The process defined in claim 3 comprising the additional steps of: selecting the predetermined scattering region for identifying time points and a predetermined scattering region for character duration and producing an indication when said scattering region for identifying time points is exceeded and when the scattering region for character duration is not reached.
Claim 6
Dependent Claim
43 words
The process defined in claim 1 comprising the additional step of: producing impulses in each group of a predetermined number of groups of frequencies, each impulse corresponding to a given group being of a different amplitude relative to the impulse for other groups.
Claim 7
Dependent Claim
19 words
The process defined in claim 5 wherein said impulses are produced by high frequency switching of an operating voltage.
