Abstract
A formatter circuit for generating pulses of a variable, in particular extremely short width comprises an input terminal (10) receiving a pulse start signal which is fed to a frequency divider circuit (11) and another input terminal (12) receiving a pulse-stop signal which is fed to a second frequency divider circuit (13). One of these frequency divider circuits generates two internal signals which are fed to a multiplexing circuitry (16, 17, 18), whereas the other frequency divider circuit generates at least one signal which is the control signal for said multiplexing circuitry. (FIG. 3).
