Title: Device for generating sawtooth signals and spectral analyser including such a device
Inventor: FUCHS JEAN-PIERRE
IPC: H03K4/02
Filed: 1983-09-09
Abstract: The present invention relates to a device capable of generating sawtooth signals for controlling, for example, the horizontal scanning of an electron tube. The sawtooth signals are obtained from pulses H whose frequency is chosen by a digitally controlled switching circuit 2. A counter mounted as a divider 3 receives the signal H and is followed by a digital-analog converter 4 which delivers a sawtooth formed of successive levels until the counter is reset to zero by an end-of-sawtooth signal R. The amplitude of the levels is controlled by a digital signal Ca, which determines the amplitude of the reference voltage Vr of the converter. Application to spectral analysers.
