Data display system with CRT - has sweep modification circuit controlled by signal modifying sweep speed of second deviation circuit

摘要

The CRT display circuit includes a sweep modification circuit controlled by a signal. This signal modifies the sweep speed of a second deviation circuit. This the distance between determined sweep lines is modified by a second space different from a first space. The sweep modification circuit alters the differences between sweep lines of a group corresponding to sweeps of the electronic beam. The circuit modifies the distance between the corresponding sweep group and one of the neighbouring sweep lines. In the first case the difference is less than a first and in the second case greater than the first.
