Abstract
A clock generator for a pulse repeater of a receiver in a pulse transmission system comprises a forward filter (1) connected to its input (A), a difference former (2) whose positive input is connected to the output of the forward filter (1), a series arrangement connected between the output of the difference former (2) and the output (B) of the clock pulse generator and comprising a limiter (3), a time differentiator (4), a rectifier (5) and a narrow bandpass filter (10) in this order, and a feedback filter (6) connected between the output of the limiter (3) or the rectifier (5) and the negative input of the difference former (2). The limiter (3) is used to cancel intersymbol interference. The clock generator can be utilized in combination with a known pulse signal regenerator (1,7-9) of the decision feedback type to constitute a pulse repeater. Alternatively, a pulse repeater can be obtained by combining the clock generator with only a pulse regenerator (8, FIG. 2) whose clock input is connected to the output (B) of the clock generator, whose signal input is connected to the output of the rectifier (5) of the clock generator and whose output constitutes the output (c) of the pulse repeater.
