Abstract: 1,039,205. Telegraphy. GERAETWERKE KARL-MARX-STADT VEB. March 19, 1964, No. 11659/64. Heading H4P. An apparatus for measurement of the bias distortion or characteristic distortion of pulses comprises the circuit in Fig. 6. Prior to the measurements meter 9 is set to full scale deflection by adjustment of resistor 4 while applying telegraph voltage at 1, contacts 3/1 and 8/1 being closed. To measure the characteristic distortion, the received pulse is applied at 2-the pulse received may, for example, be a character having only one Mark bit. Contacts 8/2 and 3/2 being closed, the pulse is differentiated at 12, 13 and one of the resultant pulses is passed by rectifier 14 and smoothed at 15, 16. Meter 9, which at zero characteristic distortion is arranged to give half-scale deflection, shows a lower reading which differs from half deflection by an amount proportional to the characteristic distortion. The bias distortion is measured by integrating the received pulse at 20, 21 and applying the result via 8/4 to the meter, to the other terminal of which the characteristic distortion voltage is applied via 10/2. The meter shows the bias distortion as the difference of these two voltages. In order to make full use of the meter scale the zero characteristic distortion scale reading referred to above is shifted to full-scale deflection by adjustment of resistor 5, contact 8/3 being closed during this operation.
